Django 1.10.3刷新后无法解析基

Question

我有一个模型开发的游乐场。在

运行python manage.py makemigrations时出错

Traceback (most recent call last):

This can happen if you are inheriting models from an app with migrations (e.g. contrib.auth)
 in an app with no migrations; see https://docs.djangoproject.com/en/1.10/topics/migrations/#dependencies for more

尽管我试了很多次，还是一直在发生：

1. 当然python manage.py makemigration <appName>
2. python manage.py migrate <appName>
3. 从应用程序中删除所有表
4. python manage.py squashmigrations main 0001
5. 清空模型.py文件
6. 在“设置”中取消对应用程序的注释
7. 读我能找到的所有东西
8. 正在刷新整个数据库python manage.py flush

你知道怎么解决这个问题吗？谢谢， 丹尼尔
