安装element: vue add element
 

修改main.js

import Vue from 'vue'

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

import App from './App.vue'

Vue.use(ElementUI)

Vue.config.productionTip = false

new Vue({
  render: h => h(App),
}).$mount('#app')

修改App.vue

<template>
  <div id="app">
    <HelloWorld msg="Welcome to Your Vue.js App"/>
  </div>
</template>

<script>
import HelloWorld from './components/HelloWorld.vue'

export default {
  name: 'app',
  components: {
    HelloWorld
  }
}
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

修改 ./components/HelloWorld.vue

<template>
  <div class="hello">
    <h1>{
   
   { msg }}</h1>
    <div>
      <img class="dlogo" :src="src" />
      <img class="dlogo" src="../assets/logo.png" />
    </div>
    <div>
      <el-image class="dlogo" :src="src"></el-image>
      <el-image class="dlogo" src="@/assets/logo.png"></el-image>
      <el-image class="dlogo" src="../assets/logo.png"></el-image>
      <el-image class="dlogo" src="/images/logo.png"></el-image>
    </div>
    
  </div>
</template>

<script>

export default {
  name: 'HelloWorld',
  props: {
    msg: String
  },
  data: function () {
    return {
      src: require('@/assets/logo.png')
      // src: "../assets/logo.png"
    }
  },

  created ()
  {
    // console.log(this.src);
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
.hello {
  display: flex;
  flex-direction: column;
}

h3 {
  margin: 40px 0 0;
}
ul {
  list-style-type: none;
  padding: 0;
}
li {
  display: inline-block;
  margin: 0 10px;
}
a {
  color: #42b983;
}

.dlogo {
  border: 1px dashed red;
  height: 100px;
}
</style>

最终浏览器上运行结果：

能正常显示的图片对应的地址是：

总结：

1. assets目录下的资源文件在使用时要用require() 处理下，因为webpack打包时路径发生了变化！

2. 只有public下的文件，是原样打包的！
