Question

我正在使用meteor 1.4.2.3并且我想导入NodeJs网络模块？我试图在服务器端使用import net from 'net';导入它，但这不起作用。网络未定义。

import net from 'net';

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

  } 
}

从一个新的meteor create项目中，以下内容适用于我。

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();

控制台中的输出：

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