设想：
我在 Django 中使用simple_history包。
在文档中，在高级使用部分“第三方模型的历史”它说，
" 要跟踪您未创建的模型的历史记录，请使用 simple_history.register 实用程序。您可以使用它来跟踪您无法控制的第三方应用程序中的模型。这是使用 simple_history.register 记录历史记录的示例-从 django.contrib.auth 应用程序跟踪用户模型”
所以我把代码放在 models.py 中（也尝试了 admin.py），如下所示：
from simple_history import register
from django.contrib.auth.models import User
register(User)
问题：当我运行python manage.py makemigrations它给出以下错误：
E:! Project\CMIT\CMITv0101\cmit001>python manage.py makemigrations
Migrations for 'auth':

我现在可以做什么来注册我的用户模型？
