代码分析vue中如何配置less

npm install --save-dev less less-loader

npm install --save-dev style-loader css-loader

<script> (function (doc, win) {  var docEl = doc.documentElement,  resizeEvt = 'orientationchange' in window ? 'orientationchange' : 'resize',  recalc = function () {   var clientWidth = docEl.clientWidth;   if (!clientWidth) return;   if (clientWidth >= 640) {   docEl.style.fontSize = '100px';   } else {   docEl.style.fontSize = 100 * (clientWidth / 640) + 'px';   }  };   if (!doc.addEventListener) return;  win.addEventListener(resizeEvt, recalc, false);  doc.addEventListener('DOMContentLoaded', recalc, false); })(document, window); </script>

{  test: //.less$/,  use: [   "style-loader",   "css-loader",   "less-loader"  ]  }

<template> <div> <p>header</p> </div></template> <script>export default { name: "headers", data() { return {}; }};</script> <style scoped>.box { height: 300/50rem; width: 200/50rem; background-color: red; font-size: 16/50 rem;}</style>
