Mopidy:ws4py Unmet

Hey guys, trying to set this up today:

Mostly all gone well, But when i attempt to load the main screen and switch to mopidy screen it complains at me of
unmet dependencies (mopidy:ws4py)

I have checked, and triple checked ws4py is installed (following directions ) But the error persists

This looks like it is the mopidy-plugin in the infoscreen project needing it So as far as I can see this isn’t really a Mopidy issue at all, as we haven’t used ws4py since 2014 or so.
