Topic: Can't install mathlibtools

Adam Topaz (Dec 27 2021 at 19:10):

I just updated my OS, and for some reason my mathlibtools installation broke. I tried reinstalling in the usual way, but I'm getting some errors. I think it is an issue with incompatible versions of something from python?

Here are my current python/pipx/pip versions

$ python --version
Python 3.10.1

$ pipx --version
0.16.4

pip --version
pip 20.3.4 from /usr/lib/python3.10/site-packages/pip (python 3.10)

And the error I get from trying to install mathlib tools with pipx:

$ pipx install mathlibtools
Fatal error from pip prevented installation. Full pip output in file:
    /home/adam/.local/pipx/logs/cmd_2021-12-27_12.09.25_pip_errors.log

Error installing mathlibtools.

The contents of that log file are

PIP STDOUT
----------

PIP STDERR
----------
/home/adam/.local/pipx/venvs/mathlibtools/bin/python: No module named pip

Does anyone have any suggestions?

Adam Topaz (Dec 27 2021 at 19:16):

Well, I don't know what the issue is, but pip install mathlibtools seems to work.

Julian Berman (Dec 27 2021 at 20:20):

That error means somehow your pipx mathlibtools virtualenv doesn't have pip installed to it -- something like pipx uninstall mathlibtools && pipx install mathlibtools should probably do something.

Julian Berman (Dec 27 2021 at 20:20):

(Basically you want it to fully recreate that virtualenv)

Adam Topaz (Dec 27 2021 at 20:22):

@Julian Berman that doesn't work -- I uninstalled mathlibtools with pipx before trying the whole thing, and pipx install still does not work (I just tried again, to verify).

Adam Topaz (Dec 27 2021 at 20:23):

Trying again now, and I can confirm that ~/.local/pipx/venvs is empty... Still doesn't work.

Hi, i have this problem and I don't know how to solve it

@Adam Topaz OK time to nuke I guess then? rm -r ~/.local/pipx/venvs/mathlibtools

Julian Berman (Dec 27 2021 at 20:56):

Followed by pipx install mathlibtools

Adam Topaz (Dec 27 2021 at 20:57):

I'll try...

Julian Berman (Dec 27 2021 at 20:57):

@Sofia Salazar hello, welcome! You should ask that in your own thread so it's more likely to be seen.

Adam Topaz (Dec 27 2021 at 20:57):

Well... as I said above, my .local/pipx/venvs folder is empty. Is it safe to just nuke .local/pipx?

Julian Berman (Dec 27 2021 at 20:58):

Ah sorry, I misread. If you don't use pipx for anything else it should be safe yeah, but the error message is suspicious in that case.

Julian Berman (Dec 27 2021 at 20:59):

/home/adam/.local/pipx/venvs/mathlibtools/bin/python: No module named pip is an error coming from an existent python, so if that directory is indeed empty, something has been deleting it in the past few minutes

Julian Berman (Dec 27 2021 at 21:00):

Can I see type -a pipx just to be sure as well?

Julian Berman (Dec 27 2021 at 21:00):

And if you know, where did you get pipx from? Your package manager or directly from PyPI or something?

Adam Topaz (Dec 27 2021 at 21:00):

It's from my package manager. I'm on arch.

Adam Topaz (Dec 27 2021 at 21:00):

I'm going to nuke pipx completely....

Julian Berman (Dec 27 2021 at 21:00):

May want to reinstall it then via pacman

Julian Berman (Dec 27 2021 at 21:00):

Yeah.

Julian Berman (Dec 27 2021 at 21:01):

I don't know what Arch does these days, but I'd suspect maybe if your Python gets upgraded that it may scrub your pipx venvs? Which would simultaneously be infuriating but also semicorrect.
