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) }
