使用 TypeScript 导入节点模块 [英] Importing node-modules with TypeScript

问题描述

我正在努力让它发挥作用，但我似乎无法在 SO 上的任何地方找到解决方案.尝试编译这个单文件应用程序时:

I'm trying to get this to work, but I can't seem to find a solution anywhere on SO. When trying to compile this single-file app:

import http = require('http')
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World
');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');

使用命令 "tsc app.ts --module 'commonjs'" 我收到以下错误(不使用 --module 标志会给我一个额外的错误，告诉我我需要它来编译外部模块):

Using the command "tsc app.ts --module 'commonjs'" I get the following error (not using the --module flag gives me an additional error telling me that I need it to compile external modules):

error TS2071: Unable to resolve external module '"http"'.
error TS2072: Module cannot be aliased to a non-module type.

推荐答案

TypeScript 需要知道 http 存在.

TypeScript needs to know that http is present.

为节点安装类型定义:

npm install @types/node

旧答案

按照这两个步骤

• 从这里下载 node.d.ts 文件:https://github.com/borisyankov/DefinitelyTyped/tree/master/node

• 在文件顶部添加:

• Download the node.d.ts file from here : https://github.com/borisyankov/DefinitelyTyped/tree/master/node

• At the top of your file add:

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

PS:查看示例测试文件:https://github.com/borisyankov/DefinitelyTyped/blob/master/node/node-tests.ts

PS: See a sample test file : https://github.com/borisyankov/DefinitelyTyped/blob/master/node/node-tests.ts
