PythonDjango-”的；验证用户模型引用模型'；%s'；尚未安装的%settings.AUTH\u用户\u模型

如果我的代码中存在任何错误（在使用LoginRequiredMixin的视图中使用的模型中的代码），例如类似以下错误：

if (True:    # <-- example bug to show how bugs like this are hidden

这使得调试代码变得非常困难。我已确定是否从我的视图中删除此行。py：

from django.contrib.auth.mixins import LoginRequiredMixin

即使我删除了使用LoginRequiredMixin的所有实例，只要导入它，它也会隐藏真正的bug并生成上面的auth错误

我读过：

我的研究表明，大多数情况下，这是由于安装的应用程序中缺少“django.contrib.auth”，您可以看到我有（settings.py snippet，django 2.2）：

完整回溯的这一部分与上述内容一致：

如果我调用makemigrations，下面是回溯（这是我所期望的）：
