node.js - Running from server.js example from nodebeginner book on heroku

Question

I am new to node.js and Heroku. I have tried to run the very first example server.js from the nodebeginner book on Heroku. The code for server.js is

var http = require("http");
http.createServer(function(request, response) {
    response.writeHead(200, {"Content-Type": "text/plain"});
    response.write("Hello World");
    response.end();
}).listen(8888);

To deploy server.js on Heroku, I have modified the files provided on https://devcenter.heroku.com/articles/nodejs

Especially, I have changed the file package.json to

{
    {
        "name": "node-example",
        "version": "0.0.1",
        "dependencies": {
        "http": "0.10.x"      <=== changed this line 
    },
        "engines": {
        "node": "0.10.x",
        "npm": "1.2.x"
    }
}

However, when I run npm install the error message

npm WARN package.json node-example@0.0.1 No repository field.
npm WARN package.json node-example@0.0.1 No readme data.
npm http GET https://registry.npmjs.org/http
npm http 404 https://registry.npmjs.org/http

So, how should I install the package "http" http://nodejs.org/api/http.html#http_http so I can use it on Heroku? Thanks a lot!

您不需要将http依赖项添加到package.json文件中——它已经是 node.js 的一部分。
