I recently have an issue trying to install anything with pip. It keeps trying older versions complaining that each one has a version mismatch, when it matches perfectly fine. This following log is from trying to upgrade pip.

~$ pip3 install --upgrade pip

It continues on like this, but the versions of the package and metadata match perfectly fine. Reinstalling python-pip through pacman also did not help.

EDIT: I was able to fix the issue by upgrading Pip as sudo (which enabled it to install system-wide)

  • Any idea what caused this issue? I have the same problem, and it happens even if I run the pip update as root.

  • No idea, frankly, but I feel that it was a catch 22 scenario. A problem in Pip at the user level (not sure how it was caused, but I think it was my fault as i was messing around with packages) stopped it being installed properly. And installing system-wide might have allowed a proper installation of the upgraded pip. I think you might benefit from uninstalling everything python/pip related, rebooting, and trying again. It's worth it to avoid the hassle in fixing it, trust me. When debugging like this goes from minutes to hours, productivity and time is lost. Or maybe I'm just impatient ;)

  • @Dinistro Furthermore I think the problem in your distroy might actually be system-wide instead of at the user level. So there's pretty much no choice but to remove everything and re-install. I'm also looking into using conda so I don't mess up package compatibility with different applications that require certain package versions. Definitely worth it to not have to run into it again. (as well as, of course, full system backups, though I try to fix it since it's quicker than finding and then restoring all of those related files from backup)

    Yeah, I was messing around with globally installed packages (C++ python bindings). I was in the end forced to reinstall pip and that resolved the issue. Thanks for your response.
