Originally created by @kifjj on GitHub (Aug 4, 2025).

New to Langchain and python.

When I run:

pip install -e .

it fails with error:

Getting requirements to build editable did not run successfully.
│ exit code: 1
╰─> [56 lines of output]
configuration error: project.scripts.langgraph-dev must be python-entrypoint-reference
DESCRIPTION:
Reference to a Python object. It is either in the form
`importable.module, or importable.module:object.attr.

  GIVEN VALUE:
      "langgraph.cli:dev_command --config ch9/py/langgraph.json --verbose"

It works when I replace:

[project.scripts]
langgraph-dev = "langgraph.cli:dev_command --config ch9/py/langgraph.json --verbose"

with:

[project.scripts]
langgraph-dev = "langgraph.cli:dev_command"

Not sure why is this happening.

Hello,
I ran into the same issue today on macOS. Same fix as always!
Don’t forget to pass the config file when running langgraph-dev, e.g. langgraph-dev --config ch9/py/langgraph.json --verbose.
Thanks everyone! :)
