ModuleNotFoundError: import of git.refs halted; None in sys.modules

Hello! Maybe some of you will be able to help. I'm currently writing something that needs to act like dependabot but for Minecraft plugins.

Here's a the current commit state that gives me this exception: ModuleNotFoundError: import of git.refs halted; None in sys.modules

Here's the console output with the debug I added to my program:

> python check_updates.py --push-to-git
update
if update == lululombard/issue1
if update not in ['lululombard/issue1', 'master']
update
if update == update
lululombard/issue1

Switching from lululombard/issue1 to update works, but not the other way around. Any idea why? Thanks.

Thanks for posting. Python being unable or not permitted to import modules is nothing I have seen before, and believe this has to do with the runtime system executing the code rather than GitPython.

Due to my inexperience with Python in general I wouldn't know how to fix that though.

Even though I am closing the issue, please feel free to keep posting in the comments section if it is relevant to GitPython. Thank you.

@Byron I found a way around the issue. I believe it was broken because it was called in the __del__() of my class. By calling it manually it works fine.

Ah, right! When something is run while Python is shutting down, nothing is guaranteed to be working anymore, sadly. It was a case in my time 10 years ago and still is the case now apparently.
