linter-flake8 with python 3 only in Majaro Qonos (21.2.6)

[Ardemus]

Is linter-flake8 reliant on python 2 being installed outside of my project's python3 venv?

I was using linter-flake8 happily in Pop!OS which still has python pointing to python 2, but I just switched to Manjaro Qonos 21.2.6 with KDE. They end of lifed python 2, and now python and python 3 both point to python 3.10.4.

Flake8 itself runs fine on my Manjaro install, but linter-flake8 is throwing errors. After a little digging, and a careful reading of the project instructions, it seems like it's designed to run on python 2.

I also dug around and there doesn't seem to be a way to install python 2 inside of a python 3 venv. You can create separate environments and switch between them, but you can put both in one environment, which I would need. I don't understand python terribly well, but the existence of virtual environments suggests that going off repo to install python 2 system-wide might just cause problems.

Am I getting this right?
