Short stacktrace, how to debug?

[ego-thales]

Hello,

I come here to ask for help because I don't know how to debug this at all.
I have the following stacktrace when trying to run pytest with uv. Everything was fine yesterday still, but since I made a few (seemingly) completely unrelated changes, I have this:

$ uv run pytest
Traceback (most recent call last):
  File "/home/me/workspace/myproject/.venv/bin/pytest", line 4, in <module>
    from pytest import console_main
  File "/home/me/workspace/myproject/.venv/lib/python3.13/site-packages/pytest/__init__.py", line 8, in <module>
    from _pytest._code import ExceptionInfo
  File "/home/me/workspace/myproject/.venv/lib/python3.13/site-packages/_pytest/_code/__init__.py", line 5, in <module>
    from .code import Code
  File "/home/me/workspace/myproject/.venv/lib/python3.13/site-packages/_pytest/_code/code.py", line 1376, in <module>
    _PLUGGY_DIR = Path(pluggy.__file__.rstrip("oc"))
                       ^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'rstrip'

The traceback starts in pytest so it doesn't help me relate this error to any change I made, so I don't know how to debug. I did look at the last file blame on github, but I could not see any relevant modification recently.

It might be due to pluggy or maybe to uv having an impact on pluggy.__file__?

Thanks in advance for your help.

Élie

Nevermind, I think it had to do with uv. I recreated my venv and it works again.
