Error in mounted hook: “TypeError: Cannot read property ‘init’ of undefined”

let myChart = this.$echarts.init(document.getElementById('radar1'))

Error reason: ecarts version is too high, after unloading. Install lower version:

cnpm install [email protected] -S

  However, it is found that there are still errors:

Error: ENOENT: no such file or directory, open

terms of settlement:

Restart the service. Recompile!

color: new echarts.graphic.LinearGradient

New is wrong

 

I changed it to this:

There is no mistake
