Ant design vue 引入echarts

          1、首先，在客户端输入：

   npm install echarts --save

         2、执行完毕后，再次编译运行

    yarn run serve

          可是结果没有想到，会报此错误：

ERROR  Failed to compile with 6 errors                                                                                                            下午3:32:56

      3、再次安装

yarn install

Done in 4.99s.

      4、再次编译运行   yarn run serve,  提示编译成功

      5、打开浏览器，访问后报JS错：

            echarts出现 “TypeError: Cannot read property ‘init‘ of undefined“报错

      6、在引入的地方把：

              import echarts from 'echarts'

            更改为： import * as echarts from 'echarts'

       刷新后，就可以看到想要的柱状图了。
