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>

开发环境截图：

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)
 }
