一、问题描述

做一个vue项目的时候，突然页面打不开了，空白页，什么都不显示
在这里插入图片描述
报这个错

The resource http://localhost:8082/js/index.js was preloaded using link preload but not used within a few seconds from the window’s load event. Please make sure it has an appropriate as value and it is preloaded intentionally.

二、解决问题

然后我寻思也没有用这个文件呀，后面找呀找呀，发现我在打包的HTML模板里加了一行注释

<!--<body><script type="text/javascript" src="../monitorScreen/js/index.js"></script></body>-->

完整HTML如下

<!DOCTYPE html>
<html lang="">
  <head>
    <meta charset="utf-8">
    <!--<meta http-equiv="X-UA-Compatible" content="IE=edge">-->
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <title>哈哈哈哈</title>

  </head>
  <body>
    <!--<noscript>-->
      <!--<strong>We're sorry but <%= htmlWebpackPlugin.options.title %> doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>-->
    <!--</noscript>-->
    <div id="app"></div>
    <!-- built files will be auto injected -->
    <!--<body><script type="text/javascript" src="../monitorScreen/js/index.js"></script></body>-->
  </body>
</html>
