Django频道错误-无法导入BACKEND'asgi_redis.RedisChannelLayer'

问题描述

我已经安装了Django-Channels，但是在运行daphne服务器时，出现以下错误：

  File /usr/local/lib/python2.7/dist-packages/channels/asgi.py，make_backend 
中的第36行，无法导入为％s指定的BACKEND％r％（self.configs [name] ['BACKEND']，名称）
 
channels.asgi.InvalidChannelLayerError：无法导入为默认
   
 
 
我的settings.py是：
  CHANNEL_LAYERS = {
默认值：{
 BACKEND： asgi_redis.RedisChannelLayer，
 CONFIG：{
 hosts：[os.environ.get（'REDIS_URL'，'redis：/ / XXXX：6379'）]，
}，
 ROUTING： MyProject.routing.channel_routing，
}，
} 
  
需要帮助来解决此错误。 
解决方案
只需安装 asgi_redis。我以为默认会在安装Django-Channels时默认安装它，但是没有。默认情况下会安装 asgiref，而不是 asgi_redis。因此，要解决此问题，只需运行即可：
 > sudo pip install asgi_redis 
  
 
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
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",
},
}
Need help in resolving this error. 
 解决方案 
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
