解决.vue文件url引用文件的问题

遇到的问题：

在css中引入图片，明明目录结构是对的，还是This dependency was not found；
dev好好的，build 之后凉凉，图片加载404

添加图片路径配置

webpack 添加 alias

//webpack.base.conf.js alias: {  '@': resolve('src'),  //加入  'assets': resolve('src/assets') }

路径书写规则

template 可使用@、~
style 只能使用~
script 只能使用@
不需要经过打包的static文件写相对路径

根据limit:10000，使用两张图片：

<template> <div>  <div>   img+src：@   <img src="@/assets/images/jiaban.jpg" height="200px">   <img src="@/assets/images/cat.png" alt="">  </div>  <div>   img+src：~   <img src="~assets/images/jiaban.jpg" height="200px">   <img src="~assets/images/cat.png" alt="">  </div>  <div>   img+js(attrs):   <img :src="jiaban" height="200px">   <img :src="cat" alt="">   <ul>    <li>{{jiaban}}</li>    <li>{{cat}}</li>   </ul>  </div>  <div class="css-bg">   img+css(background-images):   <span class="css-bg__1"></span>   <span class="css-bg__2"></span>  </div>  <div>   static：    <img src="static/images/jiaban.jpg" height="200px">   <img src="static/images/cat.png" alt="">  </div> </div></template><script>const jiaban = require('@/assets/images/jiaban.jpg');const cat = require('@/assets/images/cat.png');export default { data(){  return {   jiaban,   cat  } }}</script><style lang="scss">.css-bg__1,.css-bg__2{ display: inline-block;}.css-bg__1{ height: 200px; width: 173px; background-image: url(~assets/images/jiaban.jpg); background-size: contain;}.css-bg__2{ height: 49px; width: 49px;  background-image: url(~assets/images/cat.png); background-size: contain;}</style>

添加构建路径配置

添加ExtractTextPlugin中publicPath配置，这里根据实际情况配：

//build/util.js // Extract CSS when that option is specified // (which is the case during production build) if (options.extract) {  return ExtractTextPlugin.extract({  use: loaders,  fallback: 'vue-style-loader',  publicPath: '../../',   }) } else {  return ['vue-style-loader'].concat(loaders) }
