Pytest: ModuleNotFoundError: No module named 'importlib_metadata'

[zaufi]

I'm trying to test my plugin w/ various Python versions and the latest pytest works on Python 3.8 only. Python 3.7 and 3.6 failed with the $subj message.

The problem gone if I install importlib_metadata package "manually".

The importlib_metadata package is a dependency of pytest for Python < 3.8:

https://github.com/pytest-dev/pytest/blob/7d5f5a878598aaa7f3e100ef6a97bcd13c1b408d/setup.py#L14

pytest is expected to be installed through pip or another program which takes care to install such dependencies. If you are using another installation method, take a look at list from the link above and make sure all of the dependencies are satisfied.

I use pipenv which is supposed to be a sane install method...

For people suffering this with pipenv, search into your .lock file if ther's an importlib-metadata entrance... If you don't find it, then regenerate your .lock file again and it will be there and this will be fixed.

Yeah, somehow the problem is gone %)
Case closed.
