Daphne被正确加载了吗？

Question

我是新来的频道。我学习了聊天教程。也可以在异步模式下使用runserver命令执行所有操作。

另一方面，当我使用daphne时：(autoACIlab)$ daphne -b 10.9.6.114 -p 8000 autoACIlab.asgi:application -v 2

2019-02-11 14:06:48,352 INFO     Starting server at tcp:port=8000:interface=10.9.6.114
2019-02-11 14:06:48,352 INFO     HTTP/2 support not enabled (install the http2 and tls Twisted extras)
2019-02-11 14:06:48,352 INFO     Configuring endpoint tcp:port=8000:interface=10.9.6.114
2019-02-11 14:06:48,353 INFO     HTTPFactory starting on 8000
2019-02-11 14:06:48,353 INFO     Starting factory <daphne.http_protocol.HTTPFactory object at 0x7fefb3acdd68>
2019-02-11 14:06:48,354 INFO     Listening on TCP address 10.9.6.114:8000

在浏览器请求之后，我得到了这个错误：

2019-02-11 14:08:01,412 ERROR    Exception inside application: Cannot import BACKEND 'channels_redis.core.RedisChannelLayer' specified for default

  Cannot import BACKEND 'channels_redis.core.RedisChannelLayer' specified for default
2019-02-11 14:08:01,412 INFO     failing WebSocket opening handshake ('Internal server error')

有没有人能给我点线索？我必须更改配置文件中的某些内容吗？

谢谢。你好，卢卡

重新安装了频道-redis with pip一切都很好！

安装asgi_redis是否有帮助？：

sudo pip install asgi_redis
