Python LookupError:App'；层次结构'；不'；我没有'；CustomUser'；模型

我一直在遵循Django文档创建自定义用户模型

以下是主要错误- （编辑-我被要求添加整个回溯，所以它就在这里）

更糟糕的是，在出现下面的错误之后，我已经做了网站告诉我的一切，在任何地方都找不到答案

During handling of the above exception, another exception occurred:

我还正确地将其添加为AUTH_USER_模型，使用-

AUTH_USER_MODEL = 'Hierarchy.CustomUser'

您可以发布所有回溯吗？@ncopiy添加了完整的回溯，希望它能帮助识别错误您是否在settings.py中将“Hierarchy”添加到

已安装的应用程序中@是的，这是我们检查的第一件事，它就在那里。这个错误不应该出现，因为我无法理解它发生的原因。尝试用
Hierarchy.apps.HierarchyConfig
替换
HierarchyConfig
（检查你有一个带有
HierarchyConfig
cls的apps.py）可以发布所有回溯吗？@ncopiy添加了完整的回溯，希望它能帮助识别错误您是否在settings.py中将“层次结构”添加到
