Django Channels Error - Cannot import BACKEND 'asgi_redis.RedisChannelLayer'

Question

I have installed Django-Channels but while running the daphne-server I am getting this error given below:

File \"/usr/local/lib/python2.7/dist-packages/chann         


        

Answer 1

In my case asgiref version 2.3.2 was not compatible. I downgraded it as follows and then my code worked.

pip install asgiref==1.0.0

Answer 2

Just needed to install 'asgi_redis'. I was assuming that it would have gotten installed by default while installing Django-Channels, but it doesn't. 'asgiref' gets installed by default and not 'asgi_redis'. So to solve this issue, one can just run:

> sudo pip install asgi_redis

Answer 3

I also faced same problem while working with django-channels, by following the documentation examples https://channels.readthedocs.io/en/latest/tutorial/index.html you just need to install channels-redis as

pip install channels-redis

to resolve this issue.

Answer 4

In regard to Utkarsh's reply itt's been renamed to:

pip install channels_redis

Answer 5

With asgiref-2.3.2 and maybe more, you need to install channel_redis.

NOT asgi_redis.

pip install channel_redis

Answer 6

Faced the similar issue. Solved it by installing channels_redis:

pip install channels_redis

Also using channel redis in setting too:

CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels_redis.core.RedisChannelLayer',
        'CONFIG': {
            'hosts': [('localhost', 6379)],
        },
    },
    'ROUTING': 'ws.routing.application',
}
