Webpack捆绑的文件没有定义“要求”

我正在使用networking包捆绑一些js＆jsx文件加载到浏览器。 所有运行良好，但浏览器打开它的那一刻它logging一个错误ReferenceError: Can't find variable: require 。

我目前的configuration如下：

 var path = require('path'); var fs = require('fs'); var nodeModules = {}; fs.readdirSync('node_modules') .filter(function (x) { return ['.bin'].indexOf(x) === -1; }) .forEach(function (mod) { nodeModules[mod] = 'commonjs ' + mod; }); module.exports = [ { name: 'server', target: 'node', context: path.join(__dirname, 'src', 'cloud'), entry: ['babel-polyfill', './app.js'], output: { path: __dirname, filename: 'app.bundle.js' }, module: { loaders: [ {test: /\.jsx?$/, exclude: /node_modules/, loader: 'babel'} ] }, externals: nodeModules, node: { __dirname: true } }, { name: 'client', target: 'web', context: path.join(__dirname, 'src', 'static', 'scripts'), entry: { index: ['babel-polyfill', './index.js'] }, output: { path: path.join(__dirname, 'src', 'public', 'bundles'), filename: '[name].bundle.js' }, module: { loaders: [ {test: /\.html$/, loader: 'raw'}, {test: /\.css$/, loader: 'style'}, {test: /\.css$/, loader: 'css'}, {test: /\.jsx?$/, loader: 'babel'} ] }, externals: nodeModules } ]; 

任何想法，为什么会发生这种情况？ 提前致谢
