@SuperDicq @prma Which is why here Python libs are installed using the system package manager, then maybe PYTHON_PATH later for things like dependencies that aren't released yet.

pip is never gonna be on my machines, it's a complete disaster. For example it always executes setup.py, and no not everyone migrated to pep517 yet).
Then you have PyPI allowing completely random archives including compiled code, no idea if you can even disable that. And quite few times I've seen it fail to resolve dependencies on other people's machines…
