我在我的 Mac 上使用 Python 3.8 并开发一个应用程序两年多了。我在 PythonAnywhere 上托管这个应用程序，因为我使用的是 Sqlite3。
现在PA给我发了一封邮件，说我需要将系统镜像从Python 3.8升级到3.10。我以前从未这样做过，所以我注册了一个免费帐户并部署了完全相同的应用程序来测试该过程。
我创建了一个新项目 virtualenv 并安装了 Python 3.10 和 Django 5.0（也尝试过 3.1 - 这是我的 Mac 上的版本）。我完成了所有设置并设置了 wsgi，就像之前在其他项目中多次一样。
当我安装所有应用程序并尝试运行该网站时，我收到了很长的错误回溯：

我以前从未见过SuccessURLAllowedHostsMixin。 我不知道如何解决这个问题。难道是因为升级了Python 3.10或者Django 5.0导致的错误？
如果有人可以帮助我，请先谢谢您！
如果找到解决方案，感谢拉斐尔的评论。问题是在 Django 4.1 中，
SuccessURLAllowedHostsMixinRedirectURLMixindjango-two-factor-auth所以我降级到 Django 4.0 并且工作正常。
