RuntimeError: Model class doesn't declare an explicit app_label and isn't in an application in INST

RuntimeError: Model class  doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

我这里出现的问题，即解决方案：

setting中正确的引入了installed_apps，但依然报错。原因是我的apps.py文件中

原先是这样的

class ShopConfig(AppConfig):
    name = 'shop'
    verbos_name = '商店'

更改后可以

class ShopConfig(AppConfig):
    name = 'apps.shop'
    verbos_name = '逛逛'

记录下，具体原因后续更新

更新：不要使用相对路径
