导入nodejs模块

Question

我使用流星1.4.2.3，我想导入NodeJs网络模块？我试图在服务器端用import net from 'net';导入它，但那不起作用。 Net未定义。

import net from 'net'; 

export class Print { 
    private printAsync(callback){ 
    let client = new net.Socket(); 

    } 
}

从一个新鲜的meteor create项目，以下适用于我。

在/server/main.js：

import { Meteor } from 'meteor/meteor'; 

Meteor.startup(() => { 
    // code to run on server at startup 
}); 

import net from 'net'; 

export class Print { 
    printAsync(callback){ 
    let client = new net.Socket(); 
    console.log(client); 
    } 
} 

console.log(net); 
const print = new Print(); 
print.printAsync(); 

输出在控制台：

I20161129-07:59:18.007(-8)? { createServer: [Function], 
I20161129-07:59:18.008(-8)? createConnection: [Function],

我无法重现您不确定net。
