vue中引入echarts 报错“export ‘default‘ (imported as ‘echarts‘) was not found in ‘echarts‘

参考的是这篇博主的文章

去看了下我自己的echarts的版本号

npm ls echarts  //查看echarts的版本

一看确实是5.0的
或者在page.json文件查看（这是重装好的，仅做演示）

"dependencies": {
"axios": "^0.19.2",
"echarts": "^4.9.0",
"element-ui": "^2.13.2",
"html2canvas": "^1.0.0-rc.7",
"qrcodejs2": "^0.0.2",
"vue": "^2.5.2",
"vue-axios": "^2.1.5",
"vue-qr": "^2.2.1",
"vue-router": "^3.0.1"
},

按照这篇博主说的，卸载了重装 echarts

npm uninstall echarts //卸载

重装

npm install echarts@4.9.0
npm fund
npm run dev

 

这样就好了

 

 

 

 效果如下
