Node.js的模块在打字稿

Question

什么是必须的模块代码（以打字稿writen）看起来希望能够利用这样的：

/// <reference path="./onoff.ts" /> 

//import * as onoff from "./onoff"; 
var onoff = require("./onoff"); 

var app = onoff(); 

var computers: Onoff.Computer[] = []; 
app.start(computers); 

，我确信那一定是这一点，但它不工作：

import * as express from "express"; 
export module Onoff {  

    export class Computer { 

    } 

    export class OnoffApp { 


     start(computers:Computer[], port:number = 3489) { 
      ... 
     } 
    } 

    export default function() { 
     return new OnoffApp(); 
    } 
} 

打字稿抱怨：

service/example.ts(5,11): error TS2349: Cannot invoke an expression whose type lacks a call signature. 
service/example.ts(7,16): error TS2503: Cannot find namespace 'Onoff'. 
service/example.ts(8,21): error TS2503: Cannot find namespace 'Onoff'. 
typings/express/express.d.ts(14,1): error TS6053: File 'typings/serve-static/serve-static.d.ts' not found. 
typings/express/express.d.ts(28,34): error TS2307: Cannot find module 'serve-static'. 

非常感谢你！我不知道我做了什么错？

1. 从错误的描述来看，移动import外面你的模块应该解决您的问题：

   import * as express from "express"; 
   export module Onoff { 
       ... 
   } 
   

2. 您导入模块作为onoff但试图用Onoff

   var onoff = require("./onoff"); 
       ^
   var computers: Onoff.Computer[] = []; 
         ^
