Gmusic disabled by dependency issue

I’m try to run mopidy in raspberry pi raspbian flavor. Log show gmusic is disabled by dependency like the post https://discourse.mopidy.com/t/gmusic-extension-gets-disabled/604:

Any help is appreciated.

I realized that installing the packages with easy_install resolve the issue.
