Django 频道错误 - 无法导入 BACKEND 'asgi_redis.RedisChannelLayer' [英] Django Channels Error - Cannot import BACKEND 'asgi_redis.RedisChannelLayer'

问题描述

我已经安装了 Django-Channels，但在运行 daphne-server 时出现以下错误:

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/channels/asgi.py", line 36, in make_backend
"Cannot import BACKEND %r specified for %s" % (self.configs[name]['BACKEND'], name)

channels.asgi.InvalidChannelLayerError: Cannot import BACKEND 'asgi_redis.RedisChannelLayer' specified for default

我的 settings.py 是:

My settings.py is:

CHANNEL_LAYERS = {
"default": {
    "BACKEND": "asgi_redis.RedisChannelLayer",
    "CONFIG": {
        "hosts": [os.environ.get('REDIS_URL', 'redis://X.X.X.X:6379')],
    },
    "ROUTING": "MyProject.routing.channel_routing",
},
}

需要帮助解决此错误.

推荐答案

只需要安装'asgi_redis'.我假设它会在安装 Django-Channels 时默认安装，但事实并非如此.'asgiref' 默认安装，而不是 'asgi_redis'.因此，要解决此问题，只需运行:

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
