如何解决此 Django 管理问题？ Django admin 站点匹配查询不存在

Question

我的管理员不工作。 我已经尝试了几个小时。

迁移工作：

C:\Users\sebas\AI_MachineLearning\Django_Projekt\pythonprojects\cookbook>python manage.py migrate
Operations to perform:
  Apply all migrations: admin, auth, contenttypes, recipes, sessions, sites
Running migrations:
  No migrations to apply.

C:\Users\sebas\AI_MachineLearning\Django_Projekt\pythonprojects\cookbook>

The Superuser is created.

Runserver works:
C:\Users\sebas\AI_MachineLearning\Django_Projekt\pythonprojects\cookbook>python manage.py runserver
Watching for file changes with StatReloader
Performing system checks...

Django version 2.2.5, using settings 'cookbook.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.
