Description:
What It Does
------------
``virtualenv`` is a tool to create isolated Python environments.
The basic problem being addressed is one of dependencies and versions,
and indirectly permissions. Imagine you have an application that
needs version 1 of LibFoo, but another application requires version
2. How can you use both these applications? If you install
everything into ``/usr/lib/python2.7/site-packages`` (or whatever your
platform's standard location is), it's easy to end up in a situation
where you unintentionally upgrade an application that shouldn't be
upgraded.
Or more generally, what if you want to install an application *and
leave it be*? If an application works, any change in its libraries or
the versions of those libraries can break the application.
Also, what if you can't install packages into the global
``site-packages`` directory? For instance, on a shared host.
In all these cases, ``virtualenv`` can help you. It creates an
environment that has its own installation directories, that doesn't
share libraries with other virtualenv environments (and optionally
doesn't access the globally installed libraries either).
Installation
------------
.. warning::
We advise installing virtualenv-1.9 or greater. Prior to version 1.9, the
pip included in virtualenv did not not download from PyPI over SSL.
.. warning::
When using pip to install virtualenv, we advise using pip 1.3 or greater.
Prior to version 1.3, pip did not not download from PyPI over SSL.
.. warning::
We advise against using easy_install to install virtualenv when using
setuptools < 0.9.7, because easy_install didn't download from PyPI over SSL
and was broken in some subtle ways.
To install globally with `pip` (if you have pip 1.3 or greater installed globally):
::
$ [sudo] pip install virtualenv
Or to get the latest unreleased dev version:
::
$ [sudo] pip install https://github.com/pypa/virtualenv/tarball/develop
To install globally from source:
::
$ curl -O https://pypi.python.org/packages/source/v/virtualenv/virtualenv-X.X.tar.gz
$ tar xvfz virtualenv-X.X.tar.gz
$ cd virtualenv-X.X
$ [sudo] python setup.py install
To *use* locally from source:
::
$ curl -O https://pypi.python.org/packages/source/v/virtualenv/virtualenv-X.X.tar.gz
$ tar xvfz virtualenv-X.X.tar.gz
$ cd virtualenv-X.X
$ python virtualenv.py myVE
.. note::
The ``virtualenv.py`` script is *not* supported if run without the
necessary pip/setuptools/virtualenv distributions available locally. All
of the installation methods above include a ``virtualenv_support``
directory alongside ``virtualenv.py`` which contains a complete set of
pip and setuptools distributions, and so are fully supported.
Usage
-----
The basic usage is::
$ virtualenv ENV
This creates ``ENV/lib/pythonX.X/site-packages``, where any libraries you
install will go. It also creates ``ENV/bin/python``, which is a Python
interpreter that uses this environment. Anytime you use that interpreter
(including when a script has ``#!/path/to/ENV/bin/python`` in it) the libraries
in that environment will be used.
It also installs either `Setuptools
<http://peak.telecommunity.com/DevCenter/setuptools>`_ into the environment.
.. note::
Virtualenv (<1.10) used to provide a ``--distribute`` option to use the
setuptools fork Distribute_. Since Distribute has been merged back into
setuptools this option is now no-op, it will always use the improved
setuptools releases.
A new virtualenv also includes the `pip <http://pypi.python.org/pypi/pip>`_
installer, so you can use ``ENV/bin/pip`` to install additional packages into
the environment.
.. _Distribute: https://pypi.python.org/pypi/distribute
activate script
~~~~~~~~~~~~~~~
In a newly created virtualenv there will be a ``bin/activate`` shell
script. For Windows systems, activation scripts are provided for CMD.exe
and Powershell.
On Posix systems you can do::
$ source bin/activate
This will change your ``$PATH`` so its first entry is the virtualenv's
``bin/`` directory. (You have to use ``source`` because it changes your
shell environment in-place.) This is all it does; it's purely a
convenience. If you directly run a script or the python interpreter
from the virtualenv's ``bin/`` directory (e.g. ``path/to/env/bin/pip``
or ``/path/to/env/bin/python script.py``) there's no need for
activation.
After activating an environment you can use the function ``deactivate`` to
undo the changes to your ``$PATH``.
The ``activate`` script will also modify your shell prompt to indicate
which environment is currently active. You can disable this behavior,
which can be useful if you have your own custom prompt that already
displays the active environment name. To do so, set the
``VIRTUAL_ENV_DISABLE_PROMPT`` environment variable to any non-empty
value before running the ``activate`` script.
On Windows you just do::
> \path\to\env\Scripts\activate
And type `deactivate` to undo the changes.
Based on your active shell (CMD.exe or Powershell.exe), Windows will use
either activate.bat or activate.ps1 (as appropriate) to activate the
virtual environment. If using Powershell, see the notes about code signing
below.
.. note::
If using Powershell, the ``activate`` script is subject to the
`execution policies`_ on the system. By default on Windows 7, the system's
excution policy is set to ``Restricted``, meaning no scripts like the
``activate`` script are allowed to be executed. But that can't stop us
from changing that slightly to allow it to be executed.
In order to use the script, you have to relax your system's execution
policy to ``AllSigned``, meaning all scripts on the system must be
digitally signed to be executed. Since the virtualenv activation
script is signed by one of the authors (Jannis Leidel) this level of
the execution policy suffices. As an administrator run::
PS C:\> Set-ExecutionPolicy AllSigned
Then you'll be asked to trust the signer, when executing the script.
You will be prompted with the following::
PS C:\> virtualenv .\foo
New python executable in C:\foo\Scripts\python.exe
Installing setuptools................done.
Installing pip...................done.
PS C:\> .\foo\scripts\activate
Do you want to run software from this untrusted publisher?
File C:\foo\scripts\activate.ps1 is published by E=jannis@leidel.info,
CN=Jannis Leidel, L=Berlin, S=Berlin, C=DE, Description=581796-Gh7xfJxkxQSIO4E0
and is not trusted on your system. Only run scripts from trusted publishers.
[V] Never run [D] Do not run [R] Run once [A] Always run [?] Help
(default is "D"):A
(foo) PS C:\>
If you select ``[A] Always Run``, the certificate will be added to the
Trusted Publishers of your user account, and will be trusted in this
user's context henceforth. If you select ``[R] Run Once``, the script will
be run, but you will be prometed on a subsequent invocation. Advanced users
can add the signer's certificate to the Trusted Publishers of the Computer
account to apply to all users (though this technique is out of scope of this
document).
Alternatively, you may relax the system execution policy to allow running
of local scripts without verifying the code signature using the following::
PS C:\> Set-ExecutionPolicy RemoteSigned
Since the ``activate.ps1`` script is generated locally for each virtualenv,
it is not considered a remote script and can then be executed.

The ``--system-site-packages`` Option
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you build with ``virtualenv --system-site-packages ENV``, your virtual
environment will inherit packages from ``/usr/lib/python2.7/site-packages``
(or wherever your global site-packages directory is).
This can be used if you have control over the global site-packages directory,
and you want to depend on the packages there. If you want isolation from the
global system, do not use this flag.
Environment variables and configuration files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
virtualenv can not only be configured by passing command line options such as
``--python`` but also by two other means:
- Environment variables
Each command line option is automatically used to look for environment
variables with the name format ``VIRTUALENV_<UPPER_NAME>``. That means
the name of the command line options are capitalized and have dashes
(``'-'``) replaced with underscores (``'_'``).
For example, to automatically use a custom Python binary instead of the
one virtualenv is run with you can also set an environment variable::
$ export VIRTUALENV_PYTHON=/opt/python-3.3/bin/python
$ virtualenv ENV
It's the same as passing the option to virtualenv directly::
$ virtualenv --python=/opt/python-3.3/bin/python ENV
This also works for appending command line options, like ``--find-links``.
Just leave an empty space between the passsed values, e.g.::
$ export VIRTUALENV_EXTRA_SEARCH_DIR="/path/to/dists /path/to/other/dists"
$ virtualenv ENV
is the same as calling::
$ virtualenv --extra-search-dir=/path/to/dists --extra-search-dir=/path/to/other/dists ENV
- Config files
virtualenv also looks for a standard ini config file. On Unix and Mac OS X
that's ``$HOME/.virtualenv/virtualenv.ini`` and on Windows, it's
``%APPDATA%\virtualenv\virtualenv.ini``.
The names of the settings are derived from the long command line option,
e.g. the option ``--python`` would look like this::
[virtualenv]
python = /opt/python-3.3/bin/python
Appending options like ``--extra-search-dir`` can be written on multiple
lines::
[virtualenv]
extra-search-dir =
/path/to/dists
/path/to/other/dists
Please have a look at the output of ``virtualenv --help`` for a full list
of supported options.
Windows Notes
~~~~~~~~~~~~~
Some paths within the virtualenv are slightly different on Windows: scripts and
executables on Windows go in ``ENV\Scripts\`` instead of ``ENV/bin/`` and
libraries go in ``ENV\Lib\`` rather than ``ENV/lib/``.
To create a virtualenv under a path with spaces in it on Windows, you'll need
the `win32api <http://sourceforge.net/projects/pywin32/>`_ library installed.
PyPy Support
~~~~~~~~~~~~
Beginning with virtualenv version 1.5 `PyPy <http://pypy.org>`_ is
supported. To use PyPy 1.4 or 1.4.1, you need a version of virtualenv >= 1.5.
To use PyPy 1.5, you need a version of virtualenv >= 1.6.1.
Creating Your Own Bootstrap Scripts
-----------------------------------
While this creates an environment, it doesn't put anything into the
environment. Developers may find it useful to distribute a script
that sets up a particular environment, for example a script that
installs a particular web application.
To create a script like this, call
``virtualenv.create_bootstrap_script(extra_text)``, and write the
result to your new bootstrapping script. Here's the documentation
from the docstring:
Creates a bootstrap script, which is like this script but with
extend_parser, adjust_options, and after_install hooks.
This returns a string that (written to disk of course) can be used
as a bootstrap script with your own customizations. The script
will be the standard virtualenv.py script, with your extra text
added (your extra text should be Python code).
If you include these functions, they will be called:
``extend_parser(optparse_parser)``:
You can add or remove options from the parser here.
``adjust_options(options, args)``:
You can change options here, or change the args (if you accept
different kinds of arguments, be sure you modify ``args`` so it is
only ``[DEST_DIR]``).
``after_install(options, home_dir)``:
After everything is installed, this function is called. This
is probably the function you are most likely to use. An
example would be::
def after_install(options, home_dir):
if sys.platform == 'win32':
bin = 'Scripts'
else:
bin = 'bin'
subprocess.call([join(home_dir, bin, 'easy_install'),
'MyPackage'])
subprocess.call([join(home_dir, bin, 'my-package-script'),
'setup', home_dir])
This example immediately installs a package, and runs a setup
script from that package.
Bootstrap Example
~~~~~~~~~~~~~~~~~
Here's a more concrete example of how you could use this::
import virtualenv, textwrap
output = virtualenv.create_bootstrap_script(textwrap.dedent("""
import os, subprocess
def after_install(options, home_dir):
etc = join(home_dir, 'etc')
if not os.path.exists(etc):
os.makedirs(etc)
subprocess.call([join(home_dir, 'bin', 'easy_install'),
'BlogApplication'])
subprocess.call([join(home_dir, 'bin', 'paster'),
'make-config', 'BlogApplication',
join(etc, 'blog.ini')])
subprocess.call([join(home_dir, 'bin', 'paster'),
'setup-app', join(etc, 'blog.ini')])
"""))
f = open('blog-bootstrap.py', 'w').write(output)
Another example is available `here
<https://github.com/socialplanning/fassembler/blob/master/fassembler/create-venv-script.py>`_.
Using Virtualenv without ``bin/python``
---------------------------------------
Sometimes you can't or don't want to use the Python interpreter
created by the virtualenv. For instance, in a `mod_python
<http://www.modpython.org/>`_ or `mod_wsgi <http://www.modwsgi.org/>`_
environment, there is only one interpreter.
Luckily, it's easy. You must use the custom Python interpreter to
*install* libraries. But to *use* libraries, you just have to be sure
the path is correct. A script is available to correct the path. You
can setup the environment like::
activate_this = '/path/to/env/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
This will change ``sys.path`` and even change ``sys.prefix``, but also allow
you to use an existing interpreter. Items in your environment will show up
first on ``sys.path``, before global items. However, global items will
always be accessible (as if the ``--system-site-packages`` flag had been used
in creating the environment, whether it was or not). Also, this cannot undo
the activation of other environments, or modules that have been imported.
You shouldn't try to, for instance, activate an environment before a web
request; you should activate *one* environment as early as possible, and not
do it again in that process.
Making Environments Relocatable
-------------------------------
Note: this option is somewhat experimental, and there are probably
caveats that have not yet been identified.
.. warning::
The ``--relocatable`` option currently has a number of issues,
and is not guaranteed to work in all circumstances. It is possible
that the option will be deprecated in a future version of ``virtualenv``.
Normally environments are tied to a specific path. That means that
you cannot move an environment around or copy it to another computer.
You can fix up an environment to make it relocatable with the
command::
$ virtualenv --relocatable ENV
This will make some of the files created by setuptools use relative paths,
and will change all the scripts to use ``activate_this.py`` instead of using
the location of the Python interpreter to select the environment.
**Note:** scripts which have been made relocatable will only work if
the virtualenv is activated, specifically the python executable from
the virtualenv must be the first one on the system PATH. Also note that
the activate scripts are not currently made relocatable by
``virtualenv --relocatable``.
**Note:** you must run this after you've installed *any* packages into
the environment. If you make an environment relocatable, then
install a new package, you must run ``virtualenv --relocatable``
again.
Also, this **does not make your packages cross-platform**. You can
move the directory around, but it can only be used on other similar
computers. Some known environmental differences that can cause
incompatibilities: a different version of Python, when one platform
uses UCS2 for its internal unicode representation and another uses
UCS4 (a compile-time option), obvious platform changes like Windows
vs. Linux, or Intel vs. ARM, and if you have libraries that bind to C
libraries on the system, if those C libraries are located somewhere
different (either different versions, or a different filesystem
layout).
If you use this flag to create an environment, currently, the
``--system-site-packages`` option will be implied.
The ``--extra-search-dir`` option
---------------------------------
.. note::
Currently, this feature only partially works for pip, and not at
all for setuptools. For details,
see `Issue #327 <https://github.com/pypa/virtualenv/issues/327>`_
This option allows you to provide your own versions of setuptools
and/or pip on the filesystem, and tell virtualenv to use those distributions
instead of the ones in ``virtualenv_support``.
To use this feature, pass one or more ``--extra-search-dir`` options to
virtualenv like this::
$ virtualenv --extra-search-dir=/path/to/distributions ENV
The ``/path/to/distributions`` path should point to a directory that
contains setuptools and/or pip distributions. Setuptools distributions
must be ``.egg`` files; pip distributions should be `.tar.gz` source
distributions.
If no satisfactory local distributions are found, virtualenv will fail. Virtualenv will never download packages.
The distribution lookup is done in the following locations, with the most
recent version found used:
#. The current directory.
#. The directory where virtualenv.py is located.
#. A ``virtualenv_support`` directory relative to the directory where
virtualenv.py is located.
#. If the file being executed is not named virtualenv.py (i.e. is a boot
script), a ``virtualenv_support`` directory relative to wherever
virtualenv.py is actually installed.
Compare & Contrast with Alternatives
------------------------------------
There are several alternatives that create isolated environments:
* ``workingenv`` (which I do not suggest you use anymore) is the
predecessor to this library. It used the main Python interpreter,
but relied on setting ``$PYTHONPATH`` to activate the environment.
This causes problems when running Python scripts that aren't part of
the environment (e.g., a globally installed ``hg`` or ``bzr``). It
also conflicted a lot with Setuptools.
* `virtual-python
<http://peak.telecommunity.com/DevCenter/EasyInstall#creating-a-virtual-python>`_
is also a predecessor to this library. It uses only symlinks, so it
couldn't work on Windows. It also symlinks over the *entire*
standard library and global ``site-packages``. As a result, it
won't see new additions to the global ``site-packages``.
This script only symlinks a small portion of the standard library
into the environment, and so on Windows it is feasible to simply
copy these files over. Also, it creates a new/empty
``site-packages`` and also adds the global ``site-packages`` to the
path, so updates are tracked separately. This script also installs
Setuptools automatically, saving a step and avoiding the need for
network access.
* `zc.buildout <http://pypi.python.org/pypi/zc.buildout>`_ doesn't
create an isolated Python environment in the same style, but
achieves similar results through a declarative config file that sets
up scripts with very particular packages. As a declarative system,
it is somewhat easier to repeat and manage, but more difficult to
experiment with. ``zc.buildout`` includes the ability to setup
non-Python systems (e.g., a database server or an Apache instance).
I *strongly* recommend anyone doing application development or
deployment use one of these tools.
Contributing
------------
Refer to the `contributing to pip`_ documentation - it applies equally to
virtualenv, except that virtualenv issues should filed on the `virtualenv
repo`_ at GitHub.
Virtualenv's release schedule is tied to pip's -- each time there's a new pip
release, there will be a new virtualenv release that bundles the new version of
pip.
Files in the `virtualenv_embedded/` subdirectory are embedded into
`virtualenv.py` itself as base64-encoded strings (in order to support
single-file use of `virtualenv.py` without installing it). If your patch
changes any file in `virtualenv_embedded/`, run `bin/rebuild-script.py` to
update the embedded version of that file in `virtualenv.py`; commit that and
submit it as part of your patch / pull request.

Running the tests
~~~~~~~~~~~~~~~~~
Virtualenv's test suite is small and not yet at all comprehensive, but we aim
to grow it.
The easy way to run tests (handles test dependencies automatically)::
$ python setup.py test
If you want to run only a selection of the tests, you'll need to run them
directly with nose instead. Create a virtualenv, and install required
packages::
$ pip install nose mock
Run nosetests::
$ nosetests
Or select just a single test file to run::
$ nosetests tests.test_virtualenv

Changes & News
--------------
.. warning::
Python bugfix releases 2.6.8, 2.7.3, 3.1.5 and 3.2.3 include a change that
will cause "import random" to fail with "cannot import name urandom" on any
virtualenv created on a Unix host with an earlier release of Python
2.6/2.7/3.1/3.2, if the underlying system Python is upgraded. This is due to
the fact that a virtualenv uses the system Python's standard library but
contains its own copy of the Python interpreter, so an upgrade to the system
Python results in a mismatch between the version of the Python interpreter
and the version of the standard library. It can be fixed by removing
``$ENV/bin/python`` and re-running virtualenv on the same target directory
with the upgraded Python.
1.10.1 (2013-08-07)
~~~~~~~~~~~~~~~~~~~
* **New Signing Key** Release 1.10.1 is using a different key than normal with
fingerprint: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
* Upgraded pip to v1.4.1
* Upgraded setuptools to v0.9.8
1.10 (2013-07-23)
~~~~~~~~~~~~~~~~~
* **BACKWARDS INCOMPATIBLE** Dropped support for Python 2.5. The minimum
supported Python version is now Python 2.6.
* **BACKWARDS INCOMPATIBLE** Using ``virtualenv.py`` as an isolated script
(i.e. without an associated ``virtualenv_support`` directory) is no longer
supported for security reasons and will fail with an error.
Along with this, ``--never-download`` is now always pinned to ``True``, and
is only being maintained in the short term for backward compatibility
(Pull #412).
* **IMPORTANT** Switched to the new setuptools (v0.9.7) which has been merged
with Distribute_ again and works for Python 2 and 3 with one codebase.
The ``--distribute`` and ``--setuptools`` options are now no-op.
* Updated to pip 1.4.
* Added support for PyPy3k
* Added the option to use a version number with the ``-p`` option to get the
system copy of that Python version (Windows only)
* Removed embedded ``ez_setup.py``, ``distribute_setup.py`` and
``distribute_from_egg.py`` files as part of switching to merged setuptools.
* Fixed ``--relocatable`` to work better on Windows.
* Fixed issue with readline on Windows.
.. _Distribute: https://pypi.python.org/pypi/distribute
1.9.1 (2013-03-08)
~~~~~~~~~~~~~~~~~~
* Updated to pip 1.3.1 that fixed a major backward incompatible change of
parsing URLs to externally hosted packages that got accidentily included
in pip 1.3.
1.9 (2013-03-07)
~~~~~~~~~~~~~~~~
* Unset VIRTUAL_ENV environment variable in deactivate.bat (Pull #364)
* Upgraded distribute to 0.6.34.
* Added ``--no-setuptools`` and ``--no-pip`` options (Pull #336).
* Fixed Issue #373. virtualenv-1.8.4 was failing in cygwin (Pull #382).
* Fixed Issue #378. virtualenv is now "multiarch" aware on debian/ubuntu (Pull #379).
* Fixed issue with readline module path on pypy and OSX (Pull #374).
* Made 64bit detection compatible with Python 2.5 (Pull #393).
1.8.4 (2012-11-25)
~~~~~~~~~~~~~~~~~~
* Updated distribute to 0.6.31. This fixes #359 (numpy install regression) on
UTF-8 platforms, and provides a workaround on other platforms:
``PYTHONIOENCODING=utf8 pip install numpy``.
* When installing virtualenv via curl, don't forget to filter out arguments
the distribute setup script won't understand. Fixes #358.
* Added some more integration tests.
* Removed the unsupported embedded setuptools egg for Python 2.4 to reduce
file size.
1.8.3 (2012-11-21)
~~~~~~~~~~~~~~~~~~
* Fixed readline on OS X. Thanks minrk
* Updated distribute to 0.6.30 (improves our error reporting, plus new
distribute features and fixes). Thanks Gabriel (g2p)
* Added compatibility with multiarch Python (Python 3.3 for example). Added an
integration test. Thanks Gabriel (g2p)
* Added ability to install distribute from a user-provided egg, rather than the
bundled sdist, for better speed. Thanks Paul Moore.
* Make the creation of lib64 symlink smarter about already-existing symlink,
and more explicit about full paths. Fixes #334 and #330. Thanks Jeremy Orem.
* Give lib64 site-dir preference over lib on 64-bit systems, to avoid wrong
32-bit compiles in the venv. Fixes #328. Thanks Damien Nozay.

* Fix ``--relocatable`` when a script uses ``__future__`` imports. Thanks
Branden Rolston.
* Fix a bug in the config option parser that prevented setting negative
options with environemnt variables. Thanks Ralf Schmitt.
* Allow setting ``--no-site-packages`` from the config file.
* Use ``/usr/bin/multiarch-platform`` if available to figure out the include
directory. Thanks for the patch, Mika Laitio.
* Fix ``install_name_tool`` replacement to work on Python 3.X.
* Handle paths of users' site-packages on Mac OS X correctly when changing
the prefix.
* Updated the embedded version of distribute to 0.6.28 and pip to 1.2.
1.7.2 (2012-06-22)
~~~~~~~~~~~~~~~~~~
* Updated to distribute 0.6.27.
* Fix activate.fish on OS X. Fixes #8. Thanks David Schoonover.
* Create a virtualenv-x.x script with the Python version when installing, so
virtualenv for multiple Python versions can be installed to the same
script location. Thanks Miki Tebeka.
* Restored ability to create a virtualenv with a path longer than 78
characters, without breaking creation of virtualenvs with non-ASCII paths.
Thanks, Bradley Ayers.
* Added ability to create virtualenvs without having installed Apple's
developers tools (using an own implementation of ``install_name_tool``).
Thanks Mike Hommey.
* Fixed PyPy and Jython support on Windows. Thanks Konstantin Zemlyak.
* Added pydoc script to ease use. Thanks Marc Abramowitz. Fixes #149.
* Fixed creating a bootstrap script on Python 3. Thanks Raul Leal. Fixes #280.
* Fixed inconsistency when having set the ``PYTHONDONTWRITEBYTECODE`` env var
with the --distribute option or the ``VIRTUALENV_USE_DISTRIBUTE`` env var.
``VIRTUALENV_USE_DISTRIBUTE`` is now considered again as a legacy alias.
1.7.1.2 (2012-02-17)
~~~~~~~~~~~~~~~~~~~~
* Fixed minor issue in `--relocatable`. Thanks, Cap Petschulat.
1.7.1.1 (2012-02-16)

scheme. Thanks michr.
* Made activate script available for use with msys and cygwin on Windows.
Thanks Greg Haskins, Cliff Xuan, Jonathan Griffin and Doug Napoleone.
Fixes #176.
* Fixed creation of virtualenvs on Windows when Python is not installed for
all users. Thanks Anatoly Techtonik for report and patch and Doug
Napoleone for testing and confirmation. Fixes #87.
* Fixed creation of virtualenvs using -p in installs where some modules
that ought to be in the standard library (e.g. `readline`) are actually
installed in `site-packages` next to `virtualenv.py`. Thanks Greg Haskins
for report and fix. Fixes #167.
* Added activation script for Powershell (signed by Jannis Leidel). Many
thanks to Jason R. Coombs.
1.7 (2011-11-30)
~~~~~~~~~~~~~~~~
* Gave user-provided ``--extra-search-dir`` priority over default dirs for
finding setuptools/distribute (it already had priority for finding pip).
Thanks Ethan Jucovy.
* Updated embedded Distribute release to 0.6.24. Thanks Alex Gronholm.
* Made ``--no-site-packages`` behavior the default behavior. The
``--no-site-packages`` flag is still permitted, but displays a warning when
used. Thanks Chris McDonough.
* New flag: ``--system-site-packages``; this flag should be passed to get the
previous default global-site-package-including behavior back.
* Added ability to set command options as environment variables and options
in a ``virtualenv.ini`` file.
* Fixed various encoding related issues with paths. Thanks Gunnlaugur Thor Briem.
* Made ``virtualenv.py`` script executable.

non-default Python intepreter (by using the ``-p`` option).
* Fixed #112 - Fixed path in docs.
* Fixed #109 - Corrected doctests of a Logger method.
* Fixed #118 - Fixed creating virtualenvs on platforms that use the

1.4.8
~~~~~
* Fix for Mac OS X Framework builds that use
``--universal-archs=intel``
* Fix ``activate_this.py`` on Windows.
* Allow ``$PYTHONHOME`` to be set, so long as you use ``source
bin/activate`` it will get unset; if you leave it set and do not
activate the environment it will still break the environment.

1.4.7
~~~~~
* Include pip 0.7
1.4.6
~~~~~

``PATH`` contained a parenthesis
1.4.4
~~~~~

installed
* Fix problem with ``virtualenv --relocate`` when ``bin/`` has
subdirectories (e.g., ``bin/.svn/``); from Alan Franzoni.

~~~~~
* Fix pip installation on Windows
* Fix use of stand-alone ``virtualenv.py`` (and boot scripts)

1.4
~~~

* Added the --distribute option
* Fixed packaging problem of support-files
1.3.4
~~~~~
* Virtualenv now copies the actual embedded Python binary on
Mac OS X to fix a hang on Snow Leopard (10.6).
* Fail more gracefully on Windows when ``win32api`` is not installed.
* Fix site-packages taking precedent over Jython's ``__classpath__``
and also specially handle the new ``__pyclasspath__`` entry in
``sys.path``.
* Now copies Jython's ``registry`` file to the virtualenv if it exists.
* Better find libraries when compiling extensions on Windows.
* Create ``Scripts\pythonw.exe`` on Windows.
* Added support for the Debian/Ubuntu
``/usr/lib/pythonX.Y/dist-packages`` directory.
* Set ``distutils.sysconfig.get_config_vars()['LIBDIR']`` (based on
``sys.real_prefix``) which is reported to help building on Windows.
* Make ``deactivate`` work on ksh
* Fixes for ``--python``: make it work with ``--relocatable`` and the
symlink created to the exact Python version.
1.3.3
~~~~~
* Use Windows newlines in ``activate.bat``, which has been reported to help
when using non-ASCII directory names.
* Fixed compatibility with Jython 2.5b1.
* Added a function ``virtualenv.install_python`` for more fine-grained
access to what ``virtualenv.create_environment`` does.
* Fix `a problem <https://bugs.launchpad.net/virtualenv/+bug/241581>`_
with Windows and paths that contain spaces.
* If ``/path/to/env/.pydistutils.cfg`` exists (or
``/path/to/env/pydistutils.cfg`` on Windows systems) then ignore
``~/.pydistutils.cfg`` and use that other file instead.
* Fix ` a problem
<https://bugs.launchpad.net/virtualenv/+bug/340050>`_ picking up
some ``.so`` libraries in ``/usr/local``.
1.3.2
~~~~~
* Remove the ``[install] prefix = ...`` setting from the virtualenv
``distutils.cfg`` -- this has been causing problems for a lot of
people, in rather obscure ways.
* If you use a boot script it will attempt to import ``virtualenv``
and find a pre-downloaded Setuptools egg using that.
* Added platform-specific paths, like ``/usr/lib/pythonX.Y/plat-linux2``
1.3.1
~~~~~
* Real Python 2.6 compatibility. Backported the Python 2.6 updates to
``site.py``, including `user directories
<http://docs.python.org/dev/whatsnew/2.6.html#pep-370-per-user-site-packages-directory>`_
(this means older versions of Python will support user directories,
whether intended or not).
* Always set ``[install] prefix`` in ``distutils.cfg`` -- previously
on some platforms where a system-wide ``distutils.cfg`` was present
with a ``prefix`` setting, packages would be installed globally
(usually in ``/usr/local/lib/pythonX.Y/site-packages``).
* Sometimes Cygwin seems to leave ``.exe`` off ``sys.executable``; a
workaround is added.
* Fix ``--python`` option.
* Fixed handling of Jython environments that use a
jython-complete.jar.
1.3
~~~
* Update to Setuptools 0.6c9
* Added an option ``virtualenv --relocatable EXISTING_ENV``, which
will make an existing environment "relocatable" -- the paths will
not be absolute in scripts, ``.egg-info`` and ``.pth`` files. This
may assist in building environments that can be moved and copied.
You have to run this *after* any new packages installed.
* Added ``bin/activate_this.py``, a file you can use like
``execfile("path_to/activate_this.py",
dict(__file__="path_to/activate_this.py"))`` -- this will activate
the environment in place, similar to what `the mod_wsgi example
does <http://code.google.com/p/modwsgi/wiki/VirtualEnvironments>`_.
* For Mac framework builds of Python, the site-packages directory
``/Library/Python/X.Y/site-packages`` is added to ``sys.path``, from
Andrea Rech.
* Some platform-specific modules in Macs are added to the path now
(``plat-darwin/``, ``plat-mac/``, ``plat-mac/lib-scriptpackages``),
from Andrea Rech.
* Fixed a small Bashism in the ``bin/activate`` shell script.
* Added ``__future__`` to the list of required modules, for Python
2.3. You'll still need to backport your own ``subprocess`` module.
* Fixed the ``__classpath__`` entry in Jython's ``sys.path`` taking
precedent over virtualenv's libs.
1.2
~~~
* Added a ``--python`` option to select the Python interpreter.
* Add ``warnings`` to the modules copied over, for Python 2.6 support.
* Add ``sets`` to the module copied over for Python 2.3 (though Python
2.3 still probably doesn't work).
1.1.1
~~~~~
* Added support for Jython 2.5.
1.1
~~~
* Added support for Python 2.6.
* Fix a problem with missing ``DLLs/zlib.pyd`` on Windows. Create
* ``bin/python`` (or ``bin/python.exe``) even when you run virtualenv
with an interpreter named, e.g., ``python2.4``
* Fix MacPorts Python
* Added --unzip-setuptools option
* Update to Setuptools 0.6c8
* If the current directory is not writable, run ez_setup.py in ``/tmp``
* Copy or symlink over the ``include`` directory so that packages will
more consistently compile.
1.0
~~~
* Fix build on systems that use ``/usr/lib64``, distinct from
``/usr/lib`` (specifically CentOS x64).
* Fixed bug in ``--clear``.
* Fixed typos in ``deactivate.bat``.
* Preserve ``$PYTHONPATH`` when calling subprocesses.
0.9.2
~~~~~
* Fix include dir copying on Windows (makes compiling possible).
* Include the main ``lib-tk`` in the path.
* Patch ``distutils.sysconfig``: ``get_python_inc`` and
``get_python_lib`` to point to the global locations.
* Install ``distutils.cfg`` before Setuptools, so that system
customizations of ``distutils.cfg`` won't effect the installation.
* Add ``bin/pythonX.Y`` to the virtualenv (in addition to
``bin/python``).
* Fixed an issue with Mac Framework Python builds, and absolute paths
(from Ronald Oussoren).
0.9.1
~~~~~
* Improve ability to create a virtualenv from inside a virtualenv.
* Fix a little bug in ``bin/activate``.
* Actually get ``distutils.cfg`` to work reliably.
0.9
~~~
* Added ``lib-dynload`` and ``config`` to things that need to be
copied over in an environment.
* Copy over or symlink the ``include`` directory, so that you can
build packages that need the C headers.
* Include a ``distutils`` package, so you can locally update
``distutils.cfg`` (in ``lib/pythonX.Y/distutils/distutils.cfg``).
* Better avoid downloading Setuptools, and hitting PyPI on environment
creation.
* Fix a problem creating a ``lib64/`` directory.
* Should work on MacOSX Framework builds (the default Python
installations on Mac). Thanks to Ronald Oussoren.
0.8.4
~~~~~
* Windows installs would sometimes give errors about ``sys.prefix`` that
were inaccurate.
* Slightly prettier output.
0.8.3
~~~~~
* Added support for Windows.
0.8.2
~~~~~
* Give a better warning if you are on an unsupported platform (Mac
Framework Pythons, and Windows).
* Give error about running while inside a workingenv.
* Give better error message about Python 2.3.
0.8.1
~~~~~
Fixed packaging of the library.
