Question

我是node.js和Heroku的新手。我试图从Heroku上的nodebeginner书中运行第一个示例server.js。 server.js的代码是

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

要在Heroku上部署server.js，我修改了提供的文件 https://devcenter.heroku.com/articles/nodejs

特别是，我已将文件package.json更改为

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

但是，当我运行npm时安装错误消息

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

那么，我该如何安装软件包“http”http://nodejs.org/api/http.html#http_http 所以我可以在Heroku上使用它？非常感谢！

您不需要将http依赖项添加到package.json文件中 - 它已经是节点的一部分。

从heroku上的nodebeginner book中的server.js示例运行
