打字稿找不到模块

Question

我在Typescript中的一个文件(upload.ts)中有一个导出的模块,我无法将其导入另一个文件(application.ts)而没有错误.另外,我无法导入ExpressJS.

这是Upload.ts

/// <reference path="Main.d.ts" />

var fs = require('fs');
var path = require('path');
var formidable = require('formidable');

export class Upload{

    public parse(req, res, next) {
       ...
    }

    public save(req, res, next) {
       ...
    }

    public respond(req, res, next) {
       ...
    }

    public errors(err, req, res, next) {
       ...
    }
};

这是application.ts

/// <reference path="Main.d.ts" />

var http = require("http");
import express = require("express");
import upload = require("Upload");
var upload = new upload.Upload();

var app = express.express();
var HOST = "localhost";
var PORT = 8080;

app.use(express.logger());
app.use(app.router);

的var app = express.express();代码抛出一个错误:未解决的函数或方法明示.我从https://github.com/borisyankov/DefinitelyTyped/tree/master/express导入了express.d.ts

这是错误:

module.js:340
    throw err;
          ^
Error: Cannot find module 'upload'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Module.require (module.js:364:17)
    at require (module.js:380:17)
    at Object.<anonymous> (C:\Users\Me\WebstormProjects\untitled\server\main.js:12:14)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)

这是头文件,它引用了两个:

/// <reference path="upload.ts" />
/// <reference path="node.d.ts" />
/// <reference path="application.ts" />
/// <reference path="express.d.ts" />

Answer 1

你需要:

• 确保把两者express.d.ts并node.d.ts到项目目录中,靠近你的应用程序文件
• 将它们导入您的应用程序

例:

/// <reference path="libs/express.d.ts" />
/// <reference path="libs/node.d.ts" />

import http = require("http");
import express = require("express");
import upload = require("Upload");

var upload = new upload.Upload();
var app = express();

Upload模块可以类似的方式引用.顺便说一句,你的代码看起来更像是javascript然后打字稿
