"""Figure out where the python module needs to be placed in order to reliable import it.
|
|
|
|
Dealing with varying sys.paths is frustrating. The sys.paths in /usr are not mirrored
|
|
in /usr/local consistently. Meson uses /usr/local/python3, which ubuntus python3 does
|
|
not import from. /usr/local is ignored by python within udev. Arch does not import
|
|
from /usr/local. When in doubt, do not install into /usr/local. I do not want to deal
|
|
with ModuleNotFoundErrors. I don't care if it should be in /usr/local by convention.
|
|
I don't know how much this varies across ubuntu versions and other debian based
|
|
distributions. I want the .deb to install reliably.
