我在User中定义了自定义app.models模型。它也在AUTH_USER_MODEL设置中正确定义为app.User。当我运行网站时，一切都很完美。
然而，当我运行./manage.py syncdb --migrate时，它会突破以下追溯：

当我运行./manage.py syncdb --migrate app时，一切都正常运行，所以我不知道这里有什么。有没有人有线索？
编辑：我已安装的应用的顺序：
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 ：问题似乎是由第三方应用中的迁移引起的。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（运行所有应用程序的迁移）却没有。在构建这些信息和跟踪时，似乎在运行第三方应用程序的迁移时，我的app模型根本不可用。
