我正在开发一个名为app的django app，它是django项目的一部分，但在尝试登录admin时遇到了一些问题。

当我尝试通过localhost登录超级用户在shell中创建时出现错误：8000 / admin / login /，它显示错误：

然后显示追溯

AsgiRequest来自channels个包。因此，要么将其升级到最新版本，要么安装您正在使用的channels版本支持的django版本。因此，请尝试使用pip install channels -U将频道升级到最新版本以解决此问题。

答案 1 :(得分：0)

尝试将django频道版本升级到1.1.2，0.9.3是测试版。
