[Django]-ImportError: No module named asgi

I was able to fix this; if you are using channels 2, the channel layer is quite different from the older version.

I suggest you to try the following:

1. Confirm that you have configured your channel layer on settings.py:

   CHANNEL_LAYERS = {
       "default": {
           "BACKEND": "channels_redis.core.RedisChannelLayer",
           "CONFIG": {
               "hosts": [("redis-server-name", 6379)],
           },
       },
   }
   

   Hopefully, you have installed redis if using redis.

2. Add the channel layer to asgi.py file:

   from channels.layers import get_channel_layer
   
   channel_layer = get_channel_layer()
   

You can see this solution.

Make sure you’ve installed it and double check you’ve activated the virtualenv.

pip install -U asgi_redis

Use

pip show channels

To see the version of your package.

channels.asgi was not there until version 0.9:

https://github.com/andrewgodwin/channels/tree/0.8/channels
https://github.com/andrewgodwin/channels/tree/0.9/channels

More than likely the asgi.py file you created is in the wrong directory.

It should be in the same directory as your settings.py and wsgi.py files.

I ran into this issue when I was debugging a server and running the daphne command from the command line. I was running a command like:

/home/myuser/.virtualenvs/myapp/bin/python /home/myuser/.virtualenvs/myapp/bin/daphne -b 0.0.0.0 -p 8080  core.asgi:channel_layer

And it was still failing. Turns out I had to cd into the same directory as manage.py to get it running. If you’re using something like systemctl, you can just set the working directory to the same location.
