1、安装babel-loader
参考：http://babeljs.io/docs/setup/#installation
进入项目目录执行安装命名：
npm install --save-dev babel-loader babel-corenpm install --save-dev babel-preset-latest
babel-preset-latest 就是把所有es2015, es2016, es2017 全部包含在一起了。
2、项目结构：
app.js代码为：
import layer from ‘./components/layer/layer.js‘const App = function(){ ???const NUM=1; ???alert(NUM); ???console.log(layer)}new App()3、webpack.config.js 配置文件为
var htmlWebpackPlugin = require(‘html-webpack-plugin‘);module.exports = { ???entry: ‘./src/app.js‘, ???output: { ???????path: __dirname + ‘/dist‘, ???????filename: ‘js/[name].js‘ ???}, ???module: { ???????loaders: [{ ???????????????test: /\.js$/, ???????????????//以下目录不处理 ???????????????exclude: /node_modules/, ???????????????//只处理以下目录 ???????????????include: /src/, ???????????????????????????????loader: "babel-loader", ???????????????//配置的目标运行环境（environment）自动启用需要的 babel 插件 ???????????????query: { ???????????????????presets: [‘latest‘] ???????????????} ???????????} ???????] ???}, ???plugins: [ ???????new htmlWebpackPlugin({ ???????????template: ‘index.html‘, ???????????filename: ‘index.html‘ ???????}) ???]}4、执行命令
npm run webpack
5、编辑后的结果
webpack 编译ES6插件babel-loader
