When upgrading a package with pip it goes on an infinite loop

Question

Where is there good pip documentation? I feel like I must be stupid because pip always ends up getting screwd in every single machine/OS I use.

Whenever I try to upgrade any package pip just iterates all versions without doing anything

Why is this happening? Example

pip install -U setuptools

Terminal:

(repeat)

Can someone shed some light on what the issue might be here? This line here just makes me think pip is broken filename has '62.1.0', but metadata has '62.1.0'. I always end up with problems with pip and the documentation doesn't really help. I'm suffering. If anyone can help me with understanding pip or showing me some good documentation because I've seen colorschemes with better wikis/documentations than pip. Thank you

Error 2

This issue seems to not be that bad since pip outputs that the package is already up to date. However, my struggle with pip comes from other places. Here is another problem I would also appreciate some help

I have zscroll installed through pip, apparently, althought I installed it with paru.

Trying to upgrade it to see if the same problem would occur a different error occurs

pip install -U zscroll

Althought not as bad as an infinite loop, still makes me believe there is something either wrong with pip or with pip in my machine, which is why I have been so desperate with pip, I installed it in a fresh OS just in the morning and it already is being a pain. I just need some help to know if the problem here is me because this has been a very frequent issue I've had with pip for a long time (it breaking after a while and the documentation not helping)

Update

I have fixed this issue.

I reinstalled pip with the ensurepip python's module

python -m ensurepip --upgrade

And now I have a working pip! I am not sure what the previous problem was, I simply installed python-pip from the Arch Repository and it was kind of broken (perhaps I installed the wrong package), I also noticed that now pip is in .local/bin which I believe is where it belongs for a user installation.

Hope this can help anyone with the same issue
