If you jump from a page that has not introduced a module to a page that has introduced a module in the form of CDN, an error will be reported

[sunny-fun]

For example, I have three routing pages: / A, / B, / C

I did not introduce echarts.js in the form of CDN on the / A and / b pages; However, I introduced it locally on the / C page

<script>
export default{
    head: {
      script: [{
        src: 'https://www.xxx.xxx/echarts.min.js'
      }]
    },
}
</script>

At this time, if I forcibly refresh the page on any page of a and B (Ctrl + F5); When you jump to page C, the following error will be reported:

An error occurred while showing the error page

Unfortunately an error occurred and while showing the error page another error occurred

Error details: ReferenceError: echarts is not defined

I noticed that this was caused by not reloading the CDN JS in the head after switching the route. I want to know how to solve this problem
