我在将百日草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。已经几天没有结果了，所以我对任何和所有想法都持开放态度。

我在 python 3.4.0 django 1.7.5 上遇到了与此github 问题类似的错误。这是迁移的输出：

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 freeze 的输出：（正如我所说，它是一个现有的应用程序，所以我为它安装了其他软件包）

编辑：我觉得这与我的应用程序中的模型有关，from 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包了。
