openrazer on Gentoo
If you run into an error while compiling openrazer from the vifino-overlay, you most likely have already a later python version installed than the driver supports. The error would look something like this:
Traceback (most recent call last): File "setup.py", line 3, in <module> from setuptools import setup, find_packages ModuleNotFoundError: No module named 'setuptools'
All you need to do is temporarily set your python version to a supported version (like 3.7):
# eselect python list Available Python interpreters, in order of preference:  python3.8  python3.6  python2.7  python3.7 # eselect python set 4 # eselect python list Available Python interpreters, in order of preference:  python3.7  python3.8  python3.6  python2.7
