django.core.exceptions.AppRegistryNotReady：应用程序尚未加载，尚未在 pycharm 上启动调试

Question

我有一个使用 python 2.7.10 运行的 Django（版本 1.9）应用程序，并且我正在使用 Virtualenv。运行应用程序./manage.py runserver没有错误，但是当我尝试在调试中运行时，我得到django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

这是Pycharm调试配置：

知道为什么吗？这是完整的堆栈跟踪：

   /Users/matteobetti/Progetti/Enydros/enysoft/bin/python ./manage.py runserver
    Traceback (most recent call last):
      File "./manage.py", line 10, in <module>

    django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

我在前面加上import djangoedjango.setupexecute_from_command_line(sys.argvs)

我得到这个堆栈跟踪：

另一件要说的是，我使用 Linux 的同事使用相同的virtualenv配置没有问题，唯一有问题的是我，使用 MacO。

尝试将您的设置文件添加到系统中PATH。在我的项目中，设置位于文件夹 /project_name/project_name/settings/development.py （这与标准方式略有不同）。在我的例子中，环境变量字符串是

DJANGO_SETTINGS_MODULE=project_name.settings.development;PYTHONUNBUFFERED=1

因此，请根据您的参数进行更改，然后再次尝试运行服务器。我希望这有帮助。
