1.安装

npm install echarts --save-dev

 2.在main.js文件中引入

import * as echarts from 'echarts'

Vue.prototype.$echarts = echarts

3. 新建一个.vue文件,我是在views文件夹里建了一个Two.vue

<template>
  <div class="two">
    <div id="main" style="width: 600px;height:400px;"></div>
  </div>
</template>


<script>
import * as echarts from 'echarts';
    export default {
        name: 'two',
        data () {
            return {
                charts: '',
                opinion:['直接访问','邮件营销','联盟广告','视频广告','搜索引擎'],
                opinionData:[
                  {value:335, name:'直接访问'},
                  {value:310, name:'邮件营销'},
                  {value:234, name:'联盟广告'},
                  {value:135, name:'视频广告'},
                  {value:1548, name:'搜索引擎'}
                ]
            }
        },
        methods:{
            drawPie(id){
               this.charts = echarts.init(document.getElementById(id))
               this.charts.setOption({
                 tooltip: {
                   trigger: 'item',
                   formatter: '{a}<br/>{b}:{c} ({d}%)'
                 },
                 legend: {
                   orient: 'vertical',
                   x: 'left',
                   data:this.opinion
                 },
                 series: [
                   {
                     name:'访问来源',
                     type:'pie',
                     radius:['50%','70%'],
                     avoidLabelOverlap: false,
                     label: {
                       normal: {
                         show: false,
                         position: 'center'
                       },
                       emphasis: {
                         show: true,
                         textStyle: {
                           fontSize: '30',
                           fontWeight: 'blod'
                         }
                       }
                     },
                     labelLine: {
                       normal: {
                         show: false
                       }
                     },
                     data:this.opinionData
                   }
                 ]
               })
            }
        },
      //调用
        mounted(){
            this.$nextTick(function() {
                this.drawPie('main')
            })
        }
    }
</script>
<style scoped>
    * {
        margin: 0;
        padding: 0;
        list-style: none;
    }
</style>

4.在router文件下的index.js中写two.vue的路径

,{

    path: '/two',

    name: 'Two',

    // route level code-splitting

    // this generates a separate chunk (about.[hash].js) for this route

    // which is lazy-loaded when the route is visited.

    component: () => import(/* webpackChunkName: "about" */ '../views/Two.vue')

  }

5.在app.vue中 写那个什么来着---（忘了怎么称呼）

<router-link to="/two">Two</router-link>

然后运行npm run serve/dev就行

它的搭建基础我没有写就是vue+router+iview没写

我在运行成功之前报了特别多的错，不知道你们用时，会不会也这样，反正最后成功了
