django makemigrations 错误：TypeError: 'module' object is not iterable

错误描述：

在执行 python manage.py makemigrations 命令产生迁移文件时，抛出了 TypeError: 'module' object is not iterable 异常，具体信息如下：

TypeError: 'module' object is not iterable

Traceback (most recent call last):
  File "C:\Users\Emanuele\Desktop\Django_Env\lib\site-packages\django\urls\resolvers.py", line 591, in url_patterns
    iter(patterns)
TypeError: 'module' object is not iterable

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

    main()
  File "manage.py", line 18, in main

django.core.exceptions.ImproperlyConfigured: The included URLconf '<module 'flights.urls' from 'C:\\Users\\Emanuele\\Desktop\\Airline\\flights\\urls.py'>' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

我的解决方法：

我在总路由中有用include分发应用子路由，因此要在子应用下创建 urls.py 文件，并且里面要有urlpatterns

# 子应用/urls.py

urlpatterns = [
]

如果对你有用，请给我一个赞吧 (0。0)
