Django：迁移错误

Question

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“ unknown arguments'pk'”。 现在我无法运行管理员，出现此错误

get() got an unexpected keyword argument 'session_key'

我无法迁移，python无法理解我的models.py更改，并且在运行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):

    TypeError: get() got an unexpected keyword argument 'app_label'

突然发生了什么？ 有人能帮助我吗？
