Can't pip install pathlib on M1 Mac

Question

When I run pip install pathlib==1.0.1 I get the following error:

error: subprocess-exited-with-error

  note: This error originates from a subprocess, and is likely not a problem with pip.

Any idea how to solve the error? Version 1.0.1 is the version I need and I have seen m1 laptops with pathlib version 1.0.1 on them

pathlib has been part of the stdlib since python 3.4, see the docs and also the pypi page. Consequently, what you are seeing is just an incompatibility of installing the ancient package from pypi (2014) to a rather recent python version (3.9). You should not need to install it at all to your python version.

I don't know what the other laptopts you have seen had, but if for some reason they needed a legacy setup of e.g. python 2.7, then it would be sensible that they had pathlib installed separately via pip
