本地运行正常，部署到服务上，访问页面一片空白，开发者模式查看，发现报

<noscript>
"<strong>We're sorry but duty doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>"
</noscript>

经百度，最简单的处理方法是在vue.config.js里配置如下

publicPath: './',

vue.config.js的完整配置如下

const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
  publicPath: './',
  transpileDependencies: true
})

配置完成后，页面访问正常！！！
