Question

我尝试在空白数据库上运行基于Django 1.10的应用迁移：

python manage.py migrate --run-syncdb

但是失败了：

即使我尝试运行，我也会收到同样的错误：

python manage.py migrate contenttypes

奇怪的是，如果我跑：

python manage.py migrate django.contrib.contenttypes

然后我收到错误：

CommandError: App 'django.contrib.contenttypes' does not have migrations.

所以我无法安装内容类型的模型，因为它没有迁移......但是在内容类型的迁移完成之前我无法安装任何其他应用程序？

我做错了什么？ Django的migration docs并不是很有帮助。

由于缺少contenttypes，无法运行django迁移
