我收到了这个错误。我尝试使用migrate --fake默认但它似乎没有工作。附件是“python manage.py migrate”的输出我的设置是在OneBSD VPS上的Django 1.6 + celery3.1.12 + postgresql + gunicorn。

如果python manage.py migrate --fake-initial不起作用，您可以尝试从应用程序中删除迁移文件夹并通过以下方式创建新文件夹：
python manage.py makemigrations app_name
这对我有用：
python manage.py migrate --fake
我知道现在已经很晚了，但我在Django 1.11中遇到了这个问题。我使用table-django模型，需要另一个依赖于以前模型的TableModel。我不得不将这些从我的初始迁移中移除。
因此请检查您的迁移文件
app/migrations/some_migration.py
可能有两次引用的表。
