Can't install anything with pip

[rohtua]

Hi, I just been trying to install a new pip module and I cannot. I’m getting the below error:

Traceback (most recent call last):
  File "/usr/bin/pip", line 33, in <module>
    sys.exit(load_entry_point('pip==20.1.1', 'console_scripts', 'pip')())

    from pip._vendor.contextlib2 import ExitStack
ModuleNotFoundError: No module named 'pip._vendor.contextlib2'

I’ve checked that python-contextlib2 is installed and it is there (it imports just fine in the python console) but pip can’t see it when attempting to install modules. It’s doing it for every package I can’t even run pip install --upgrade pip. All that happens is I get the above output. I’ve tried removing and reinstalling pip and python with pacman and no luck.

From what I can find online this seems to be related to an issue with a pip upgrade. So I’ve then tried downgrading pip to V18.1 but I’m getting the same error on every version or an error about the correct version of pip not being present.

I’ve installed python and pip from the repositories so I’ve avoided trying to install manually with get-pip.py to avoid creating other errors.

Any help would be greatly appreciated.

Hopefully you did not use sudo pip ...
This might help

Why Manjaro ships pip packages as python-x?

The name come from the Arch packaging guidelines: Python package guidelines - ArchWiki For Python 3 library modules, use python-modulename . Also use the prefix if the package provides a program that is strongly coupled to the Python ecosystem (e.g. pip or tox ). For other applications, use only the program name. The same is valid for Perl, PHP, Ruby, nodejs, etc… The Arch package python-pylint is installed system wide pip install pylint Will install pylint in user mode (~/.local/) and…

No I wasn’t using sudo pip although I have tried it since and it gives the same error. It was working a few weeks ago but I haven’t tried to install anything since then so I’m assuming that an update somewhere has broken something in the meantime.

I have also tried copying the site-packages folder from /usr/lib/python3.8 and putting it in /home/$USER/.local/lib/python3.8 again I just get the same result.

Everything I’ve been able to find online would suggest that an update to pip has caused something to break but the solutions I’ve found don’t work. i.e reinstalling pip and python, removing the pip folder from site-packages and reinstalling, downgrading pip to other versions and making sure the site-packages folder is identical in both /usr/lib/python3.8 and /home/$USER/.local/lib/python3.8 to see if there was any difference in the packages.

I’ve had a bit of a break through. I’ve removed the python-pip package and installed pip using the get-pip.py script and that’s working to install modules although I am now getting a pop up asking me to create a KDEwallet every time I run pip which appears to be a known bug with the latest version (pip + twine installed: pip attempts to continuously create and use a "keyring" · Issue #8090 · pypa/pip · GitHub) but odd as I don’t have KDE on my machine I’m using the default XFCE install. Although I have installed KDenlive so it could have pulled down a few other KDE packages I suppose.

I just been trying to install a new pip module and I cannot.

Which module?

The one I originally tried was uk-covid19 (uk-covid19 · PyPI) but I was getting the same error for any module I tried to install including pip install --upgrade pip both as a standard user and using sudo.
