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);

var app = express.express();代码抛出错误：未解析的函数或方法表达。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" />

你需要：

确保将express.d.ts和node.d.ts放入项目目录中，靠近应用程序文件
将它们导入您的应用程序

示例：

/// <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();

可以以类似的方式引用

Upload模块。顺便说一下，你的代码看起来更像是javascript然后打字稿

打字稿找不到模块
