Please give a look at the FAQ section of the README

Ah yes ;) I saw this comment in another issue, why I returned here in the first place.

Unfortunately on my system running the commands as in

AttributeError: module 'attr' has no attribute 's'

Please note that attrs (with s) has not been uninstalled, since it derives from the system installation and is outside of the /usr (as it says, despite being in /usr; well).

This might be an issue with my Python environment, after all. I should try reproducing this within a dedicated pyenv, Poetry, conda or asdf environment.

[gnebbia]

Wait there is no attrs installed? Yes please retry with a clean environment.

[almereyda]

Apparently, attrs is installed, but cannot be deleted (due to the lack of sudo):

Found existing installation: attrs 21.2.0
Not uninstalling attrs at /usr/lib/python3/dist-packages, outside environment /usr
Can't uninstall 'attrs'. No files were found to uninstall.

Working with a dedicated environment seems advisable here, as you suggest.
