Django 1.9:Django.core.exceptions.AppRegistryNotReady:应用程序不'；还没装呢

我正在尝试在我的应用程序中使用此应用程序。我的Django版本是1.9。我得到以下错误：

我已经按照所有的指示去做了，但我不知道出了什么问题。请帮助我。

您正在使用的应用程序已经好几年没有更新了，并且似乎不支持Django 1.9。您可以使用不同的应用程序，也可以尝试将其更新以使用Django 1.9

回溯的这一部分显示它在

\uuuu init\uuuu.py

中导入

signals.py

，它尝试在加载应用程序之前导入模型

  File "/home/bewithaman/Projects/Event-Management-System/chance/__init__.py", line 1, in <module>
    from chance import signals
  File "/home/bewithaman/Projects/Event-Management-System/chance/signals.py", line 7, in <module>
    from chance.models import Registration

然后创建一个

change/apps.py

文件，并定义一个app config类，该类在

ready（）

方法中导入信号

from django.apps import AppConfig

class ChanceConfig(AppConfig):

    def ready(self):
        from . import signals

最后，更新

已安装的应用程序设置以使用配置

INSTALLED_APPS = [
    ...
    'chance.apps.ChanceConfig',
    ...
]
