Inside your user app, you should have a folder migrations. It should only contain 0001_initial.pyand __init__.py. Is that correct?
在您的用户应用程序中，您应该有一个文件夹migrations。它应该只包含0001_initial.py和__init__.py。那是对的吗？
Try running ./manage.py sqlmigrate user 0001_initialand see what it does, because thats where the error comes from
尝试运行./manage.py sqlmigrate user 0001_initial看看它做了什么，因为那是错误的来源

Another issue can also be the fact that you were using the database for another application. So if this can be the case just drop the database before making migrations again
另一个问题也可能是您将数据库用于另一个应用程序。因此，如果是这种情况，请在再次迁移之前删除数据库
