python - 使用通道 2 运行服务器时无法导入 ASGI_APPLICATION 模块

问题描述

我已按照频道教程进行操作，但在运行这些错误时抛出

包的版本是 channels==2.1.2 Django==2.0.4

我错过了什么？ 在 settings.py

INSTALLED_APPS = [
   "channels"
    ....
]

ROOT_URLCONF = 'myapp.urls'
ASGI_APPLICATION = "myapp.routing.application"

添加文件 mayapp/routing.py

from channels.routing import ProtocolTypeRouter 

application = ProtocolTypeRouter({
    # Empty for now (http->django views is added by default)
})

这是错误日志

解决方案

在我的情况下，在不同的文件中导入错误。

你应该做的是

python manage.py shell
from mysite.routing import application

查看它产生的确切错误并尝试修复它
