Hello @miaozhunjiayou! I'm Dosu, your friendly bot here to help you solve bugs, answer questions, and guide you as a contributor. I'm here to assist you while we wait for a human maintainer. How can I help you today?

The error message you're encountering suggests that the pyproject.toml file might be missing required fields such as [project.version] or [tool.process.version]. This is necessary for Poetry to properly configure the environment.

To resolve this issue, you should check the pyproject.toml file in your project directory and ensure that it includes the necessary version specifications. Here's a basic example of what the pyproject.toml might need:

[tool.poetry]
name = "your-project-name"
version = "0.1.0"
description = "Your project description"
authors = ["Your Name <your.email@example.com>"]

[tool.poetry.dependencies]
python = ">=3.12,<3.13"

Make sure that the [tool.poetry] section includes a version field. If this section is missing or incomplete, add the necessary fields and values. After updating the file, try running the poetry env use 3.12 command again.

If the issue persists, you might want to check if there are any specific instructions or configurations required for your version of Poetry or the Dify project.

To continue talking to Dosu, mention @dosu.

@dosubot[bot] commented on GitHub (Apr 28, 2025):

The error you're encountering, AttributeError: type object 'datetime.datetime' has no attribute 'datetime', typically occurs when there's a misuse of the datetime module in Python. This error suggests that somewhere in the code, datetime.datetime is being incorrectly referenced as datetime.datetime.datetime.

To resolve this issue, check the code where the datetime module is being used. Ensure that you are correctly importing and using the datetime class. The correct usage should look like this:

from datetime import datetime

# Example usage
current_time = datetime.now()

If the code mistakenly uses datetime.datetime.datetime, it should be corrected to datetime.datetime or simply datetime if imported directly as shown above.

Review the relevant parts of your codebase where datetime is used and make sure the import statements and usage are correct. If you need further assistance, please provide the specific code snippet where the error occurs.

Hi @miaozhunjiayou, please use this command, replace poetry to uv你好，请使用这个命令，将 poetry 替换为 uv

uv run flask run --host 0.0.0.0 --port=5001 --debug

uv run celery -A app.celery worker -P gevent -c 1 --loglevel INFO -Q dataset,generation,mail,ops_trace,app_deletion

Thank you, I followed your suggestion, but it still produces errors

When I continue to execute poetry run flag run -- host 0.0.0.0-- port=5001-- debug, there will still be errors: AttributeError: type object 'datetime.datetime' has no attribute 'datetime’ @dosu

+1.

uv run flask run --host 0.0.0.0 --port=5001 --debug it works, but i do want use miniconda3 instead uv venv.

I use miniconda env, but i use uv pip install -r pyproject.toml to download packages. Then i use flask run --host 0.0.0.0 --port=5001 --debug to start the dify api worker, got the same error. how do i fix it?
