Cannot access `.cache` file

I have setup env vars but still getting this error

❯ python3 spotifypod.py
Couldn't read cache at: .cache
Couldn't read cache at: .cache

Thank you @utkut I appreciate all the help.

I also was having two nights of trouble getting the .cache file. In my case the solution turned out to be simple–install a browser on the Pi Zero. I don’t believe this step was mentioned in the guides. From past experience I thought Midori might be a good lightweight browser to install but it took some time because of the many dependencies. Also, it really taxes the Pi Zero, so to speed thing up a lot, I popped the SD card from the Zero into a Pi 4 and Midori ran at an acceptable speed. It was called automatically when I tried to run the spotifypod.py script and I had to log into spotify to approve the authorization. This only needs to be done once (unless you somehow erase the .cache file). I don’t think the browser gets called again, which is fortunate given how many resources it takes up.

If you get an “address already in use” error, just reboot the Pi. Also, as mentioned above the environment variables need to be set, particularly paying attention that the SPOTIPY_REDIRECT_URI matches the redirect URI you entered into your project in developer.spotify.com exactly.

Finally, at least one of the following commands needs to be uncommented–i.e., active–in spotifypod.py (the second calls the first, so no need for both):

spotify_manager.refresh_devices() spotify_manager.refresh_data()
