Python Django随Zinia迁移-InvalidBasesError:无法解析[<；ModelState:'；zinnia.Author'；>；]的基

我在向现有的django应用程序添加Zinia博客应用程序时遇到一些问题。 已经有几天没有结果了，所以我对任何想法都持开放态度

我在Python3.4.0 django 1.7.5上遇到了类似的错误。 这是migrate的输出：

(project)username@computername:~/project/application$ python manage.py migrate

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/1.7/topics/migrations/#dependencies for more

编辑： 我觉得这与我应用程序中的一个模型有关，该模型来自django.contrib.auth.models import AbstractBaseUser、PermissionsMixin、UserManager

但我无法想象不在我的应用程序中使用它。也许是时候寻找另一个博客软件包了。

我已经试着安装在一个全新的博客软件包上，效果非常好。所以我不认为是我的环境出了问题。嘿@felipe我在迁移百日草的过程中也遇到了同样的错误，你们是如何解决这个问题的？您安装了fresh django项目吗？您好@OmPrakash，我们没有解决它，因为我们的项目需求在解决之前发生了变化。对不起，我帮不了你。
