npm install echarts --save

// main.js文件中引入并全局注册
import Echarts from 'echarts'
Vue.prototype.echarts = Echarts
Vue.use(Echarts)

下面在项目里就可以直接使用echars了 正常是这样的 不过可能会报错（“export ‘default‘ (imported as ‘echarts‘) was not found in ‘echarts‘…） 就是echart并没引入进来 这时候 有可能是因为echarts的版本过高 执行下面解决问题

npm ls echarts  //查看echarts的版本

npm uninstall echarts //卸载

npm install echarts@4.9.0
npm fund
npm run dev

下面就可使用啦！

html

<div style="width: 300px; height: 300px;" ref="echarts"></div>

vue 项目的话 直接在mounted中调用这个函数即可

    initCharts() {
      let self = this
      let myChart = this.echarts.init(this.$refs.echarts)
      console.log(this.$refs.chart) // 绘制图表
      let option = {
        // title: {
        //   text: 'ADP_NP.log',
        // },
        color: ['#66b1ff'],
