I downgraded my pip but I can’t upgrade anymore

I am making a game in python, it would automatically pip install the packages needed. but sometimes, the users pip is not up to date, and it won’t work(I am actually using Automator on mac) so in Automator I made it so it would pip install the latest pip version, to test it, I downgraded my pip version to 9.0.1 and now I can’t upgrade my pip version anymore, it would just leave an error saying:

Traceback (most recent call last):

ImportError: cannot import name 'Mapping' from 'collections' (/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/collections/__init__.py)

During handling of the above exception, another exception occurred:

I tried uninstalling pip but it just gave practically the same error

This is extremely far out of date.

If that’s why you wanted to use an older version of Pip - because newer versions broke an old way of doing it - the code was taking a fundamentally wrong approach. It is not intended for the Pip code to be imported and used as a library. Instead, use the subprocess standard library module to run a separate process to run Pip as an application.

I would say to try upgrading urllib3 first, but it seems unlikely that this would work, for obvious reasons.

I don’t know how you managed to downgrade Pip that far in 3.11. I don’t think it should have allowed you to try.

At this point I think you are better off reinstalling that Python version.

Try python -m ensurepip --upgrade. You may or may not need to run that as root (via sudo).
