[Solved] Gmusic, mopidy as service, pysan1 error


First post here, and I’ll start with thanking the devs for letting me turn my RBPi 3 into a music player.

I’m running Raspbian (Stretch), and I’ve installed mopidy and gmusic. Everything is working perfectly as I run mopidy as a user, but Gmusic extension fails to load when running mopidy as a service.

Here is the log:

I have seen something similar in another thread somewhere now cannot find it. Am I right in thinking that something to do with pysan1 mustn’t be available to the service, and maybe wasn’t installed correctly? I have tried to retrace my steps and install everything with sudo, but I can’t seem to be able to shake the error. Next course of action is reinstall everything from scratch unless someone can point me in the right direction?

Thanks for reading.

Normally you would run sudo mopidyctl deps to show all the versions and locations. Perhaps you could try comparing that with mopidy deps to see the difference. https://docs.mopidy.com/en/latest/troubleshooting/

Solution here I think; https://github.com/mopidy/mopidy-gmusic/issues/180

Thank you both for your quick reply.

I think I must be missing something very basic.
@Steve_Lambert thank you, that’s the thread I saw yesterday and tried to replicate the fix, without luck. See below.

When running

sudo mopidyctl deps

I still get:

pyasn1<0.5.0,>=0.4.1: not found
pyasn1>=0.1.7: 0.3.4 from /usr/local/lib/python2.7/dist-packages

Please help a newb, thanks in advance.


sudo pip install pyasn1==0.4.3

fixed the problem. Thank you for your help!
