版本和地址

1. ElementUI 2.15.14 (https://element.eleme.io/)
2. 按需引入的插件 babel-plugin-component(1.1.1) https://github.com/ElementUI/babel-plugin-component

安装

npm install element-ui

完整引入(不建议)

 这种方式最后打包的源文件很大，造成网络资源的浪费

1. main.js

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

//全局引入element-ui
Vue.use(ElementUI)

2) 增加测试代码 tests/ElGlobalTest.vue

<template>
  <el-row>
  <el-button>默认按钮</el-button>
  <el-button type="primary">主要按钮</el-button>
  <el-button type="success">成功按钮</el-button>
  <el-button type="info">信息按钮</el-button>
  <el-button type="warning">警告按钮</el-button>
  <el-button type="danger">危险按钮</el-button>
</el-row>
</template>

3) 修改App.vue

<template>
  <div id="app">
    <!-- <img alt="Vue logo" src="./assets/logo.png"> -->
    <!-- <HelloWorld msg="Welcome to Your Vue.js App"/> -->
    <ElGlobalTest></ElGlobalTest>
  </div>
</template>

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

export default {
  name: 'App',
  components: {
    // HelloWorld,
    ElGlobalTest
  }
}
</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>

4) 执行 npm run serve 查看效果

按需引入

1. 安装插件
   此插件是ElementUI改造

npm install babel-plugin-component -D

2. 修改babel的配置 babel.config.js (原来的是.babelrc)
   新版本(babel.config.js)

{
  'presets': [['@babel/preset-env', { 'modules': false }]],
  'plugins': [
    [
      "component",
      {
        "libraryName": "element-ui",
        "styleLibraryName": "theme-chalk"
      }
    ]
  ]
}

旧版本（.babelrc）

{
  'presets': [["es2015", { "modules": false }]],
  "plugins": [
    [
      "component",
      {
        "libraryName": "element-ui",
        "styleLibraryName": "theme-chalk"
      }
    ]
  ]
}

3. 修改main.js

import { Row, Button } from 'element-ui';

//按需引入element-ui的组件
Vue.use(Row)
Vue.use(Button)

4) tests/ElGlobalTest.vue 和 App.vue不变
5) 重新运行项目，查看结果
