I installed Mopidy via apt. I was able to run mopidy, but I installed the mopidy-spotify extension. I installed the extension using pip with python 3. After installing this, mopidy exited with the error:
ERROR: Mopidy requires Python 2.7, but found 3.5.3.
I think a configuration changed when installing via pip.
I tried to deinstall the spotify extension, but it did not resolve the issue.
I saw a thread, which had a similar issue. There was a suggestion to use it with a virtual environment, but unfortunately that also did not work.
Any idea how to get Mopidy to use the older version again?
