为什么不是我的babel-loader发送？ 我已添加：let x ='LOL';的console.log（X）;到我的src/main.js。 它不输出任何错误并创建输出文件。但它不会将es6语法转换为es5。babel-loader没有发生错误并且没有错误
这是我的src/main.js
var css = require('./styles.scss');
console.log('hello planet!');
let x = 'LOL';
console.log(x);
和我的输出文件DIST/bundle.min.js看起来像这样（让未启用到VAR）：
/******/ (function(modules) { // webpackBootstrap
/******/ // The module cache
/******/ var installedModules = {};
/******/
/******/ // The require function
