python - Django 自定义用户在同步数据库时在运行时遇到导入问题

Question

我在 app.models 中定义了一个自定义 User 模型。它还在 AUTH_USER_MODEL 设置中正确定义为 app.User。当我运行该网站时，一切都运行良好。

但是，当我运行 ./manage.pysyncdb --migrate 时，它会因以下回溯而中断:

Traceback (most recent call last):
  File ".virtualenv/lib/python2.7/site-packages/django/core/management/base.py", line 222, in run_from_argv

    raise CommandError("One or more models did not validate:\n%s" % error_text)
CommandError: One or more models did not validate:
auth.user: Model has been swapped out for 'app.User' which has not been installed or is abstract.

当我运行 ./manage.pysyncdb --migrate app 时，一切都运行正常，所以我不明白这里发生了什么。有人知道吗？

编辑:我安装的应用程序的顺序:

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.admin',
    'django.contrib.webdesign',
    'django.contrib.staticfiles',
    'djcelery',
    'app',

    'babeldjango',
    'debug_toolbar',
    'template_timings_panel',
    'devserver',
    'django_extensions',
    'djrill',
    'facebook_tag',
    'gunicorn',
    'haystack',
    'markitup',
    'modeltranslation',
    'raven.contrib.django',
    'reversion',
    'rosetta',
    'sorl.thumbnail',
    'south',
    'statictastic',
    'storages',
    'twitter_tag',
    'zebra',
    'djcelery',
    'djmoney_rates'
)

编辑 2:该问题似乎是由第三方应用程序中运行的迁移引起的。如果我注释掉那些有迁移的应用程序，一切都会顺利进行。我想这也是预期的，因为 ./manage.py migrate app 工作正常，但 ./manage.py migrate (为所有应用程序运行迁移)却不能。根据这些信息和跟踪，当第三方应用程序的迁移运行时，我的应用程序的模型似乎根本不可用。

遇到同样的问题，从 South 0.8.3 迁移到 South 0.8.4 解决了
