没有窗口对象目前webpack nodejs

Question

我使用webpack与babel编译我的ecmascript 6代码。一切工作正常，但如果我添加某些依赖像请求npm包一样。下面是我的文件：

main.js

import os from 'os' 

export class User { 

    constructor(username) { 
    this.username = username; 
    } 

    register() { 
    console.log("registering..."); 
    } 
} 

var client = new User("hey") 


console.log(user.register()); 

的WebPack配置：

var webpack = require('webpack') 

module.exports = { 
    entry: [ 
    './src/main.js' 
    ], 
    output: { 
    path: "dist", 
    publicPath: "/dist/", 
    filename: "stela.js" 
    }, 
    watch: false, 
    module: { 
    loaders: [{ 
     test: /\.js$/, 
     // excluding some local linked packages. 
     // for normal use cases only node_modules is needed. 
     exclude: /node_modules/, 
     loader: 'babel' 
    }, { 
     test: /\.json$/, 
     loader: 'json-loader' 
    }] 
    }, 
    externals: { 
    fs: '{}', 
    tls: '{}', 
    net: '{}', 
    console: '{}' 
    }, 
    babel: { 
    presets: ['es2015'], 
    plugins: ['transform-runtime'] 
    }, 
    resolve: { 
    modulesDirectories: ['node_modules'] 
    } 
} 

现在，如果我跑webpack，然后运行node dist/stella.js一切正常，它记录了registering...;但是，如果我添加一定的依赖性，如requests NPM包：

... 
import request from 'request' 
... 

我跑webpack一切编译下来，没有错误，但后来我尝试运行node dist/stella.js，我得到这个错误：

throw new Error('no window object present');

默认，Webpack设置为定位浏览器，而不是Node环境。尝试在您的配置中设置target：

module.exports = { 
    // ... 
    target: "node", 
    // ... 
}
