我已经将我的django从2.2更新到3.0，但是问题没有发生，请做一些事情，asgi.py文件是由我创建的，我只想让服务器识别路由应用程序并开始工作--我遵循了第2频道教程，但是我在运行之后会得到这个错误，但是我在运行之后会得到这个错误--我已经遵循了第2频道教程，但是我在运行之后得到了这个错误

# WSGI_APPLICATION = 'myproject.wsgi.application'
ASGI_APPLICATION = 'asgi.application'

注意，WSGI示例是如何具有项目名称的？我怀疑你需要在设置中包括项目名称，例如，

ASGI_APPLICATION = 'projectname.asgi.application' 

通道文档似乎支持这种格式(https://channels.readthedocs.io/en/stable/installation.html)
