我将我的项目移到另一个环境中，在安装依赖项并尝试运行 manage.py runserver - devserver 后，在请求静态文件时出现以下错误。坦率地说，我对这个错误完全迷失了，有人知道这是怎么回事吗？

    HTTP GET /static/admin/css/responsive.css 500 [0.21, 127.0.0.1:59982]
Exception inside application: async_to_sync can only be applied to async functions.
Traceback (most recent call last):

    raise TypeError("async_to_sync can only be applied to async functions.")
TypeError: async_to_sync can only be applied to async functions.

我几乎不知道问题可能出在哪里，因为我不知道这与我自己的代码有什么关系。如果我注释掉频道，其他一切都正常。

Edit2根据 ladruas 的回答降级到 asgiref==3.2.10 也对我有用。

频道之间似乎存在不兼容==3.0.3 asgiref==3.3.10
