lru_cache error in Mopidy 3

[greggilbert]

Edit: I had a different question here before, so I'm reusing the issue.

I've got Mopidy 3 running in a virtualenv with Python 3.8 on Ubuntu 18.04. When I try to start Mopidy with this extension installed, I get this error:

ERROR    2020-02-27 00:39:22,235 [15843:MainThread] mopidy.__main__
  Extension tidal failed during setup. This might have left the registry in a bad state.
Traceback (most recent call last):

    from lru_cache import SearchCache
ModuleNotFoundError: No module named 'lru_cache'

I have lru_cache installed, though:

# python -m pip show lru_cache

Any idea what's up?

Update: I just needed to use the latest version (i.e. not the one in pypi).

If anyone else finds this, I solved this by running pip install --upgrade git+https://github.com/tehkillerbee/mopidy-tidal.git@master
