Redis ERR unknown command 'BZPOPMIN'
Solution 1:
I think the problem is in the compatibility with version of the channels-redis package! I had already tested channels some time ago and it worked beautifully with channels-redis version 2.4.2, recently they are in version 3.0.1 and this version doesn't work properly yet I don't know why.
Try install the version 2.4.2 with pip:
pip install channels-redis==2.4.2
Solution 2:
Use redis 5.0.9. It worked for for the same error.
Get it from github.com/tporadowski/redis/releases
Solution 3:
Just download the latest version of Redis for Windows https://github.com/tporadowski/redis/releases from here it will work.
you don't need to downgrade the version of your channels-redis etc. This problem with Redis not with any python packages at all.
