ImportError: cannot import name 'DEFAULT_CHANNEL_LAYER'

See original GitHub issue

I cannot say I’m good at submitting issues etc. But I’m going to try it. So I hope this will help. I just faced an error when I’m trying to run the databinding example which is in your channels-examples repo.

My channels version is 0.17.2 and I installed it from pip. Here is the error:

Did you by chance use pip install django_channels? I did the same at first. Try pip install channels.

This other project shares the same namespace: https://github.com/ymyzk/django-channels
