1.下载模块

npm install vue-router

2.在src根目录下新建router文件夹，下面新增一个modules文件夹存放不同模块的路由，再建一个router.js作为路由入口文件

import Vue from "vue";
import VueRouter from "vue-router";
Vue.use(VueRouter);
import index from "./modules/indexRouter"
export default new VueRouter({
    routes:[
        ... index
    ]
})

3.在main.js中导入路由模块

这里的变量名必须是小写，大写将会报错

import Vue from 'vue'
import router from './router/router'
    new Vue({
        router,
        render: h => h(App)
    }).$mount('#app')

4.在modules文件夹下自己的模块里写路由拦截

export default[
    { path: '/', component: ()=>import('../../views/index') },
    { path: '/index', component: ()=>import('../../views/index') }
]
