unable to run pip

[Skaperen]

This will also install all dependencies.

it did not do that for me. perhaps a dependency (package) was defective and lacked the module being accessed. or perhaps the module reference was faulty for a depricated module. i tried to determine the package name with the intent to purge that package to let the install of python3-pip bring in the latest and hopefully correct dependency, but i could not determine that.

i'm working on ways to determine Ubuntu package names and dependencies. the intent is to make a command to force re-install of a package's entire dependency tree.

i will download pip by another means and see if that is different.

Which Ubuntu distribution are you using?

Yesterday I installed a Linux Mint 20.3 (based on Ubuntu 20.04) on a notebook. the installation of pip worked perfectly.

[Skaperen]

Xubuntu 20.04.4, has Python 3.8.10 and Xfce 4.14. recent fresh install. have most backups of previous Xubuntu 18.04.6.

[Axel_Erfurt]

Mint 20.3

Kernel 5.13.0-51
python 3.8.10
xfce 4.16

pip 22.1.2

[Skaperen]

is there a .deb file for pip?

maybe i should try mint for my next distro install. does it run lightdm?

[Axel_Erfurt]

You can download the deb file using

apt download python3-pip

[Skaperen]

i would need to reconfigure to get the Mint .deb. i don't want the Ubuntu .deb as that is the one that doesn't work for me.

[Axel_Erfurt]

It is not listed at http://packages.linuxmint.com/list.php?release=una.

So the package from Ubuntu is probably used in Mint.

[Skaperen]

then it is unclear why pip is failing.

[Skaperen]

i can do the import being tried by pip, so it is not the case of a missing module.

since pip works fine elsewhere, something else must be causing this specific import error as seen in post #1.

sorry i don't have numpy, yet. let me try installing it:

i can't import that one, myself:

maybe that really is missing. but "pip._vendor" is there since i could do appdirs. it just isn't making any sense what is really happening. it sure seems like the pip that comes with Ubuntu is broken. so i am looking for a copy of pip i can download into a non-distro Linux (e.g. no repository, like a Linux for those who build C stuff from source).
