我在将zinnia博客应用程序添加到现有的django应用程序时遇到了一些问题。 已经过了几天没有结果，所以我对所有想法持开放态度。
我在python 3.4.0 django 1.7.5上遇到类似的错误github issue。 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
同样，我使用的是python 3.4.0 django 1.7.5和最新版本的百日草（0.15.1）。
这是我的pip冻结的输出： （正如我所说，它是一个现有的应用程序，所以我安装了其他软件包）

修改：
我觉得这与我在我的应用程序中具有from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, UserManager
的模型有关
但我无法想象在我的应用中不使用它。也许现在是时候寻找另一个博客包了。
