Question

我阅读了许多具有相同情况的类似文章，并尝试了一些与它们完全相关的建议。我刚刚更新到Django 1.9，并收到了以下回溯：

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/opt/django/www/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 350, in execute_from_command_line
    utility.execute()
  File "/opt/django/www/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 302, in execute
    settings.INSTALLED_APPS

    self._setup(name)

    self._wrapped = Settings(settings_module)
  File "/opt/django/www/local/lib/python2.7/site-packages/django/conf/__init__.py", line 99, in __init__
    mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)

    import management
  File "/opt/django/www/src/site_aggrigator/management/__init__.py", line 4, in <module>
    from django.contrib.auth.models import Permission
  File "/opt/django/www/local/lib/python2.7/site-packages/django/contrib/auth/models.py", line 4, in <module>
    from django.contrib.auth.base_user import AbstractBaseUser, BaseUserManager
  File "/opt/django/www/local/lib/python2.7/site-packages/django/contrib/auth/base_user.py", line 49, in <module>
    class AbstractBaseUser(models.Model):
  File "/opt/django/www/local/lib/python2.7/site-packages/django/db/models/base.py", line 94, in __new__
    app_config = apps.get_containing_app_config(module)
  File "/opt/django/www/local/lib/python2.7/site-packages/django/apps/registry.py", line 239, in get_containing_app_config
    self.check_apps_ready()
  File "/opt/django/www/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.

确保所有我的应用程序都已安装在虚拟环境中，因为在进行更新之前，该应用程序运行良好。在更新之前，我也收到了此消息：

/opt/django/www/local/lib/python2.7/site-packages/Django-1.8-py2.7.egg/django/contrib/auth/models.py:41: RemovedInDjango19Warning: Model class django.contrib.auth.models.Permission doesn't declare an explicit app_label and either isn't in an application in INSTALLED_APPS or else was imported before its application was loaded. This will no longer be supported in Django 1.9.
  class Permission(models.Model):

一个帖子提供了以下解决方案： INSTALLED_APPS = ( "django.contrib.auth.models.Permission",

我也按照他们所说的那样做了可行的解决方案。其他人有这个问题吗？

Answer 1

尝试添加此内容（在SECRET_KEY声明之后）：

import django
django.setup()

Django从更新到1.9后提高了AppRegistryNotReady
