很长时间以来，我一直无法找到上述错误的解决方案。我看了几个其他类似的问题，但无法弄清楚。如果有人能指出正确的方向，我将非常感激。 确切的错误如下：

applications / users / apps.py
from django.apps import AppConfig
class CustomUsersConfig(AppConfig):
name = 'applications.users'
label = "users"
我认为也可能是此错误的线索之一是，当我将INSTALLED_APP中的“” applications.users.apps.CustomUsersConfig“更改为” users“时，错误更改为
"RuntimeError: Model class applications.users.models.User doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS."
我认为这意味着Django在根目录中检测到一个未在INSTALLED_APP中注册的名为“用户”的应用。因此，当我在INSTALLED_APP中添加“用户”并删除“ applications.users.apps.CustomUsersConfig”时，Django随后会在“应用程序/用户”中检测该模型。但是，我在项目根目录中没有“用户”应用。
任何帮助或线索，将不胜感激。
答案 0 :(得分：0)
我在用户应用旁边的另一个应用进行了类似的设置，从而收到此错误。我将用户模型导入：
from users.model import User
并通过以下操作对其进行修复：
from applications.users.model import User
