Django 1.7升级错误：AppRegistryNotReady：应用程序尚未加载
我正在尝试从Django 1.6升级到1.7。 我得到以下错误：

任何想法可能会导致错误，以及如何解决它？
UPDATE1：
我replace了：
from django.contrib.auth.models import User
至：
from django.conf import settings User = settings.AUTH_USER_MODEL
我得到以下错误：

更新2：
我replace了：
from django.contrib.auth.models import User
至：
from django.contrib.auth import get_user_model User = get_user_model()
和：
models.ForeignKey(settings.AUTH_USER_MODEL)

升级到Django 1.7时，我有类似（相同？）的问题。 在这种情况下，更新wsgi文件就足够了：replace
import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler()
同
from django.core.wsgi import get_wsgi_application application = get_wsgi_application()
见http://django.readthedocs.org/en/latest/releases/1.7.html#standalone-scripts
import django django.setup()
我正在通过所有这些线程来寻找芹菜在窗户上工作（与这个特定的错误消息），我只是想强调推
import django django.setup()
在你的tasks.py文件的最上面，这终究是为我工作的。
INSTALLED_APPS在数组中有一个缺失的逗号，导致了我的错误。
当我试图从应用程序的__init__.py导入模型时，我得到了这个错误，这是不可能的。
在configurationuwsgi应用程序文件（如uwsgi.ini）中replace：
module = django.core.handlers.wsgi:WSGIHandler()
上
module=django.core.wsgi:get_wsgi_application()
settings.AUTH_USER_MODEL是一个string（这就是为什么你得到AttributeError: 'str' object has no attribute '_meta' – 它期望一个模型），只能用于ForeignKey声明：
类文章（models.Model）：
author = models.ForeignKey（settings.AUTH_USER_MODEL）
如果你想在其他地方引用你的用户模型，你需要使用get_user_model ：
从django.contrib.auth导入get_user_model UserModel = get_user_model（）
我搬到不同的电脑时出现这个错误，忘了在我的venv中安装psycopg2 ，并在我的设置中使用'ENGINE': 'django.db.backends.postgresql', 。
也许这可能对别人有用。
就我而言，我忘了在INSTALLED_APPS里添加一个子应用程序。
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'basketball', 'basketball.area', 'basketball.game', 'basketball.player', ]
只需使用命令行重新安装Django，而不是在Pycharm帮助我。
这可能是任何原因。 在我的情况下，我更新了我的虚拟环境以外的python版本，但是我的virtualenv仍然是旧版本，这使得错误。 我删除了env，并使用更新的版本再次构build，并且工作。
