javascript - 为什么 webpack require（'request'）服务器端之类的模块会报错？

问题描述

问 题

测试文件只是很简单的：

    
var request = require('request');
var crypto = require('crypto');

但是会报错：

    ERROR in ./~/.npminstall/tough-cookie/2.3.1/tough-cookie/package.json
Module parse failed: C:\Users\Administrator\Desktop\submail\submail\node_modules
You may need an appropriate loader to handle this file type.

解决方案

npm install --save-dev json-loader

webpack配置也要修改

module.exports = {
  entry: 'index',
  output: {
    path: path.join(__dirname, 'scripts'),
    filename: 'bundle.js'
  },
  module: {
    loaders: [
      { test: /\.json$/, loader: 'json-loader' }
    ]
  },
  resolve: {
    extensions: ['', '.webpack.js', '.web.js', '.js']
  },
  node: {
    console: 'empty',
    fs: 'empty',
    net: 'empty',
    tls: 'empty'
  }
};
