Deploy Django channels ImportError: cannot import name 'DEFAULT_CHANNEL_LAYER' from 'channels'

1

Hi, I’ve been trying to deploy a django asgi webapp but at the end of the process it shows the following message:

ImportError: cannot import name ‘DEFAULT_CHANNEL_LAYER’ from ‘channels’ (/opt/render/project/src/.venv/lib/python3.11/site-packages/channels/init.py)

from what I’ve googled I understand this is related to channels/daphne packages installation, is it? or could be a misconfiguration on setting.py, etc?

Any help on how to solve thi issue will be highly welcomed.

Hi there,

Have you read through this Github thread for some potential solutions yet? https://github.com/django/channels/issues/295

Beyond that, I recommend reaching out to a community that specializes in Django, as this is not likely an issue caused by the Render platform.

Hey, thanks for your answer. Yes, I did check that github thread. I should’ve pointed out that when I run the app in my local machine in works just fine. But once I try to depoy it on render it throws the error.

Hence I guess there’s something wrong with my deployment on Render. I first deployed the site as wsgi for testing and it worked. Once I changed to asgi this problem occurred.

In case is useful to anyone. It got fixed by uninstalling all channels/daphne/redis libraries on my local machine, reinstall with python -m pip install -U ‘channels[daphne]’ command, and then re deploy.
