工头不会开始.我没有Ruby,Heroku或Foreman的经验,也没有任何网络编程经验,所以我完全不知道这里发生了什么.这是我得到的错误消息,运行Windows 7 64位：

谷歌正在躲避我.任何搜索都无法找到答案.我重新启动,重新安装,重写,重新复制,重读等等,我找不到解决方案.我的代码完全反映了上面链接的“入门”页面上的代码,为方便起见,我将在此处粘贴：

Procfile：

web: node web.js

web.js

var express = require("express");
var logfmt = require("logfmt");
var app = express();
 
app.use(logfmt.requestLogger());
 
app.get('/',function(req,res) {
  res.send('Hello World!');
});
 
var port = Number(process.env.PORT || 5000);
app.listen(port,function() {
  console.log("Listening on " + port);
});

packge.json

再次,我完全按照“入门”页面上的内容进行操作,但是工头拒绝启动.这里发生了什么？
