【问题描述】：

我在 virtualenv 中的 python 3.4 上运行 Django 1.9。它一直在工作，但今天却不行。

当我运行 ./manage.py runserver 时，我收到以下错误：

(django1)dan@danvb:~/Share/django1/suorganizer$ ./manage.py runserver
Performing system checks...

我卸载并重新安装了 Django==1.9，得到了同样的错误。在 lib/python3.4/site-packages/django/core/ 中，我没有迁移目录。我不确定要寻找什么。命令 ./manage.py runserver 不久前在这个项目上为我工作。

谢谢。

【问题讨论】：

你的INSTALLED_APPS设置的内容是什么？

【解决方案1】：

解决了。

在我有一个 Django 迁移文件夹 core/migrations/ 中，我没有实际删除迁移模块，而是将其重命名为 xxx.delete，我想我可能想恢复它。在实际删除该模块后，我的 ImportError 得到了解决。
