排除了节点模块的Webpack错误-仍然出现错误

Question

嗨，我正在为Webpack捆绑Node。

var path = require('path');
var nodeExternals = require('webpack-node-externals');

module.exports = {
  entry: './src/main.js',
  target: 'node',
  output: {
    path: path.join(__dirname, 'build'),
    filename: 'bundle.js'
  },
  externals: [nodeExternals()],
    module: {
        loaders: [
            { test: /\.js$/, loader: 'babel-loader', exclude: /node_modules/ },
            { test: /\.jsx$/, loader: 'babel-loader', exclude: /node_modules/ }
        ]
    }
}

此代码引用了在各种环境中下游使用的几个节点模块。

构建失败并显示：

如何让Webpack忽略这些而让我进行构建？
