用vue脚手架创建好项目，进行以下操作
①下载vant插件
在终端或cmd中运行
npm i vant -S
在main.js中全局配置vant
import Vant from 'vant'; import 'vant/lib/index.css'; Vue.use(Vant);
②下载安装axios
在终端或cmd中运行
npm install axios -S
在main.js中全局配置axios
import axios from 'axios' Vue.prototype.$axios = axios
③在views中创建Carts.vue(购物车页面)，Classify.vue(商品分类)，Goodslist.vue(商品列表),Index.vue,Main.vue(首页),Myself.vue(我的),Search.vue(搜索页面)
④在router下的index.js配置路由
const routes = [ { path: '/', name: 'Index', component: () => import(
'../views/Index.vue'), redirect:'/main', children:[ { path: '/main', name:
'Main', component: () => import( '../views/Main.vue') }, { path: '/classify',
name: 'Classify', component: () => import( '../views/Classify.vue') }, { path:
'/carts', name: 'Carts', component: () => import( '../views/Carts.vue') }, {
path: '/myself', name: 'Myself', component: () => import(
'../views/Myself.vue') }, ] }, { path: '/search', name: 'Search', component: ()
=> import( '../views/Search.vue') }, { path: '/list', name: 'Goodlist',
component: () => import( '../views/Goodlist.vue') } ]
