I am not sure what I did. I was configuring the config.yaml file while trying each one as I go, then all of a sudden I started getting this error in the terminal:

Traceback (most recent call last):
File “/home/thomas/.local/bin/beet”, line 7, in
from beets.ui import main
ModuleNotFoundError: No module named ‘beets’

Now it happens with every command I try, even with ‘beets ls’
OS: Ubuntu 18.04
And I think v1.3.17 of Beets

It really seems like you need to reinstall beets!

Sorry that I did not get back here any sooner, but that is what I ended up doing. I renamed my config file to config.yaml.bak, reinstalled beets then renamed the config file back to config.yaml… Im just glad that I JUST downloaded beets and didnt make many changes… but thanks anyway, everything is working great so far!
