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

TypeError: 'module' object is not iterable
The above exception was the direct cause of the following exception:

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 = [
]
