python - Django：迁移错误

问题描述

我有一个 Django 项目。一切正常，直到突然出现一些奇怪的错误，例如“未知参数'pk'”。现在我无法运行管理员，我收到此错误

get() got an unexpected keyword argument 'session_key'

我无法迁移，python 无法理解我的 models.py 更改，当我运行 makemigrations 命令时出现此错误：

    Operations to perform:
      Apply all migrations: admin, auth, contenttypes, sessions
    Running migrations:
      No migrations to apply.
    Traceback (most recent call last):
