django创建音乐网站项目时，urls.py写入代码后，pycharm一直报错： No module named 'index.urls'
用idle运行时候就报错：
Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

创建过程中只修改了urls.py 和setting.py 文件
代码如下：
urls.py

from django.contrib import admin
from django.urls import path, include
from django.conf.urls import url
from django.views import static
from django.conf import settings

# 配置URL地址信息
urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('index.urls')),
    path('ranking.html', include('ranking.urls')),
    path('play/', include('play.urls')),
    path('comment/', include('comment.urls')),
    path('search/', include('search.urls')),
    path('user/', include('user.urls')),
]

已解决：在app下添加urls.py就可以了
