我正在使用Django 1.7.5，并尝试构建pinax-project-teams启动程序。运行时python manage.py check，我被`django.core.exceptions.AppRegistryNotReady：尚未加载。
我已经在StackOverflow和其他地方阅读了无数类似的错误，并且似乎该错误是由多种原因引起的，并且往往涉及针对特定情况的修复程序。因此，我可以提前删除几个解决方案：1）这不是从先前的Django版本升级而来；和2）结果wsgi.py是正确使用了更新的from django.core.wsgi import get_wsgi_application。
完整的堆栈跟踪：
(env)trevor@nikola:webapp.git$ python manage.py check
Traceback (most recent call last):
File "manage.py", line 9, in <module>
startup.run()
File "/Users/trevor/zenith/webapp.git/djangoapp/startup.py", line 22, in run
admin.autodiscover()
File "/usr/local/lib/python2.7/site-packages/django/contrib/admin/__init__.py", line 23, in autodiscover
autodiscover_modules('admin', register_to=site)
File "/usr/local/lib/python2.7/site-packages/django/utils/module_loading.py", line 67, in autodiscover_modules
for app_config in apps.get_app_configs():
File "/usr/local/lib/python2.7/site-packages/django/apps/registry.py", line 137, in get_app_configs
self.check_apps_ready()
File "/usr/local/lib/python2.7/site-packages/django/apps/registry.py", line 124, in check_apps_ready
raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.
错误源于pinax startup.run()，它由两个调用组成：autoload(["receivers"])在settings.INSTALLED_APPS和中加载模块admin.autodiscover()。这是自动加载：
def autoload(submodules):
for app in settings.INSTALLED_APPS:
mod = import_module(app)
# print('Module: \t\n%s' % str(mod))
for submodule in submodules:
# print('Submodule: \t\n%s\n' % str(submodule))
try:
import_module("{0}.{1}".format(app, submodule))
except:
if module_has_submodule(mod, submodule):
raise
这将INSTALLED_APPS成功并成功导入所有列出的应用程序，但随后立即admin.autodiscover()引发该Apps aren't loaded yet.消息。我不确定我缺少什么...可能很明显！
哦，最后：我已经阅读了此import django; django.setup()修复程序，但是我认为这是针对脚本和交互式的，而不是针对django项目的？因为我已经尝试过以交互方式运行，所以导入我的项目设置，运行configure（），运行django.setup（）并退出，但是当我尝试执行runserver时，这对上述问题没有影响...：-/任何想法？
编辑-更新和摘要： pinax-project-teams代码与Django 1.7不完全兼容，至少在新Django项目的初始“原始”安装中不兼容。解决方法包括几个步骤：
startup.py（第21行，在中run()）删除显式/冗余应用程序加载：注释掉或删除admin.autodiscover()。pip install Django==1.6.5）。python manage.py syncdb）同步数据库。pip install Django==1.7.5）。原始答案：我认为我已经缩小了范围，至少在根本原因上。尽管我的项目不是从Django <= 1.6到1.7的升级，但这仍然是一个问题。pinax-project-team中的某项默认情况下使其与Django 1.7不兼容。相同的安装将允许进行安装syncdb，然后再runserver进行1.6.5 django安装，但django-1.7.5会抛出Apps aren't loaded yet。
我找到了很多不错的Django 1.7发行说明，我将通过它们来确定是否可以确定不兼容的原因。
至少其中一个问题是Pinax的“额外”自动发现功能startup.py，该功能自1.7版本开始在Django自己的启动过程中自动执行。这似乎解决了应用程序加载问题，但是...中还有另一个问题django.contrib.sites。migrate在1.7中运行时，迁移之一由于数据库中缺少表而失败，特别是django_site（下面的完整跟踪）。该表确实存在于1.6 django安装的数据库中。修改1.7的设置以指向1.6项目中的sqlite文件可以解决此问题，并且可以正常工作。因此，这是我在pinax-project-teams和Django 1.7之间发现的仅有的两个冲突。
