使用webpack和babel时报错

Question

初学webpack，用babel将es6转化为es5时报错：ERROR in ./entry.jsModule build failed: Error: Cannot find module 'core-js/library/fn/get-iterator'重装babel-core也不管用webpack配置为：module.exports = {    entry: './entry.js',    output: {        filename: 'bundle.js'    },    //devtool: 'source-map',    module: {        loaders: [{            test: /\.css$/,            loader: 'style-loader!css-loader'        },{            test: /\.js$/,            exclude: /node_modules/,            loader: 'babel-loader'        }]    }}.babelrc内容为：{"presets": ["es2015"]}entry.js为：var a = require('./a.js');require('./index.css');let app = document.getElementById('app');app.innerHTML = '<p>hello webpack!</p>' + a.a;

Answer 1

答案网上很多,但是可以告诉你的是 babel 即便把es6转换成es5 兼容ie的时候 也会有问题...慎用
