1，安装scss插件

cnpm i node-sass sass-loader -S

2，安装element-ui

cnpm i element-ui -S

main.js中引入element-ui

import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
Vue.use(ElementUI)

3，项目结构

App.vue

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
}
*{
  margin: 0;
  padding: 0;
}
</style>

main.js

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'

import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
Vue.use(ElementUI)

Vue.config.productionTip = false

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

 router文件夹下的index.js

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../views/Home.vue'

Vue.use(VueRouter)

const routes = [
