爲什麼不是我的babel-loader發送? 我已添加:let x ='LOL';的console.log(X);到我的src/main.js。 它不輸出任何錯誤並創建輸出文件。但它不會將es6語法轉換爲es5。babel-loader沒有發生錯誤並且沒有錯誤

這是我的src/main.js

var css = require('./styles.scss'); 

console.log('hello planet!'); 

let x = 'LOL'; 
console.log(x); 

和我的輸出文件DIST/bundle.min.js看起來像這樣(讓未啓用到VAR):

/******/ (function(modules) { // webpackBootstrap 
/******/ // The module cache 
/******/ var installedModules = {};

您的規則數組只包含一條規則,其中您使用兩次testuse屬性。結果對象只包含上次看到的定義的值,因此您只有.scss規則。你想在數組中有兩個不同的對象,每個對象都是不同的規則。

module: { 
    rules: [ 
     { 
      test: /\.js$/, 
      exclude: /(node_modules|bower_components)/, 
      use: { 
       loader: 'babel-loader', 
       options: { 
        presets: ['env'] 
       } 
      } 
     }, 
     { 
      test: /\.scss$/, 
      use: ExtractTextPlugin.extract({ 
       fallback: 'style-loader', 
       use: ['css-loader', 'sass-loader'], 
       publicPath: "/dist" 
      }) 
     } 
    ] 
},
