Python Django+；测试类型问题：AppRegistryNotReadyException

我一直在尝试Django的Testipie，但遇到了一个AppRegistryNotReady异常。我找到了一些方法来解决这个问题，但没有任何帮助

• Python:3.6
• Django:2.1.2
• django-tastypie:0.14.2

已安装的应用程序

服务/_初始化_.py

服务/应用程序.py

我得到了回溯：

可能有人已经遇到了这个问题？

尝试用

default\u-app\u-config='services.apps.ServicesConfig'替换“default\u-app\u-config='services.apps.AppConfig'

我找到了解决这个问题的方法。您应该对services/apps.py进行一些更改

谢谢你的回答，但不幸的是它仍然不起作用。

`default_app_config = 'services.apps.ServicesConfig'`
