一、安装echarts

npm install echarts --save

二、main.js引入注册

import Vue from "vue";

import * as echarts from "echarts";

Vue.prototype.$echarts = echarts;

三、vue文件中使用echarts

<template>
    <div class="page-warp">
      
       <div ref="mapEchart" class="map-box"></div>
    </div>
</template>

<script>
import geoJson from "地图数据json文件";

                },
            ],
