Question

我正在尝试在我的Ubuntu 15.04上安装djangoCMS。首先我有一个“枕头没有编译jpeg”的问题，但设法通过安装另一个pip版本（pip install Pillow == 2.3）解决它，然后再运行djangocms -f -p . myproject.

Running migrations:
      Rendering model states...Traceback (most recent call last):

    AttributeError: 'NoneType' object has no attribute '_meta'

任何人都可以向我解释原因吗？以及如何解决？谢谢！

这个问题在django-cms的support / 3.1.x分支中得到解决。您可以签出或等待下一个版本：3.1.3标记。
