尚未加载模型/未定义密钥

Question

好的：我试图使用./manage.py makemigrations命令，但是得到两个错误中的任何一个。在

1. 如果我不注释掉第三行，就会得到一个错误，即没有定义密钥。django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

2. 但是，如果我注释掉它，我得到的错误是django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet。

到目前为止，我认为中间件类中可能存在重复，但我找不到它（之前的一篇文章提到过）。所以，现在我被困在这个圈子里了。我是遗漏了什么，还是重复了什么？（这个应用程序是为uni项目设计的，叫做“chitchatapp”）。 谨致问候
