Mopidy fails to load extensions with additional dependencies

[jgillich]

Mopidy fails to load extensions that have additional dependencies. mopidy-spotify fails because it depends on pyspotify:

mopidy[2776]: INFO     Disabled extension spotify: Dependency The 'pyspotify<1.999,>=1.9' distribution was not found and is required by the application not found

I guess this is because only the extension path is added to PYTHONPATH and not the path of any sub-dependencies, but I don't know much about Python.

I suggest using http://nixos.org/nixpkgs/manual/#ssec-python-build-env

I got mopidy-spotify working at home a couple days ago but haven't made a PR for the changes yet. I'll do that tonight (~8hrs from now)

@spwhitt That is great to hear 👍

@jgillich Just ran into this problem by rebasing onto a more recent nixpkgs, I see what you're talking about now. I'm working around it for now by adding the extra dependencies to mopidy's package, but I'll look into @domenkozar 's suggestion if I find time..
