没有名为django.urls的模块

Question

我正在尝试创建一个新模型，我将其命名为产品，并且发现了以下您在下面看到的错误消息

请注意，我的Django版本是1.8.7

## urls.py：

from django.contrib import admin
from mySecondGdgBlogs import views
from django.urls import include, path
from myGdgBlogs import views
urlpatterns = [
    path('admin/', admin.site.urls),
    path('writeafterme/',include('mySecondGdgBlogs.urlss')),
    path('htm/', views.htamal),
    path('dp/',views.dpmain)
]

## views.py：

from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
def dbmain(request):
    data = ''
    return HttpResponse(data)

## models.py

from django.db import models
# Create your models here.
class Products(models.Model):
    name = models.CharField (max_length=20)
    price = models.IntegerField()
    type=models.CharField(max_length=20,choices=(
        ('S', 'Small'),
        ('M', 'Medium'),
        ('L', 'Large'),
    ))
    class Meta:
        db_table = 'Products'

我希望给我看白页，但是在浏览器中的实际结果是：
