学习Django的时候url为什么显示空路径呢，APP下的urls和项目的url都配置了

APP下的urls配置

from django.urls import path

from Study_1 import views

urlpatterns = [
path('index/', views.index, name='index'),
]

项目下的urls配置
from django.contrib import admin
from django.urls import path
from django.conf.urls import include

urlpatterns = [
path('Study_1/',include('Study_1.urls')),
path('admin/', admin.site.urls),

]

运行网页后依旧报出
Using the URLconf defined in djangoProject.urls, Django tried these URL patterns, in this order:

Study_1/
admin/
The empty path didn’t match any of these.

提示Study_1/已经有这个路由了，访问127.0.0.1/Study_1/index试试
