尝试将我的第一个node.js应用程序部署到Heroku时,Web dynos一直崩溃

$foreman start

创建与我的工作应用程序的链接
我有一个名为procfile的文件,其中包含：@H_197_9@

web: node server.js

这是我的package.json@H_197_9@

{
  "name": "node-example","version": "0.0.1","dependencies": {
    "express": "3.1.0","jade": "*","socket.io": "*","underscore": "*"
  }
}

所以我开始用“dynos”开始@H_197_9@

$heroku ps:scale web=1
Scaling web dynos... done,Now running 1


$heroku ps
=== web (1X): `node server.js`
web.1: restarTing 2013/09/27 22:10:44 (~ 34s ago)

一会儿@H_197_9@

$heroku ps
=== web (1X): `node server.js`
web.1: crashed 2013/09/27 22:11:49 (~ 10s ago)

关于我从哪里去的任何想法？@H_197_9@

编辑：这是一些日志@H_197_9@

var portx = process.env.PORT;  // This is my addition

var express = require("express"),app = express(),http = require("http").createServer(app),io = require("socket.io").listen(http),_ = require("underscore");

var participants = []

app.set("ipaddr","127.0.0.1");

app.set("port",portX);  // to here

app.set("views",__dirname + "/views");
app.set("view ENGIne","jade");
app.use(express.static("public",__dirname + "/public"));
app.use(express.bodyParser());
app.get("/",function(request,responsE) {

  response.render("index");

});

app.post("/message",responsE) {

  var message = request.body.message;

  if(_.isUndefined(messagE) || _.isEmpty(message.trim())) {
    return response.json(400,{error: "message is invalid"});
  }

  var name = request.body.name;
  io.sockets.emit("incomingmessage",{message: message,name: namE});
  response.json(200,{message: "message received"});
});

io.on("connection",function(socket){

  socket.on("newUser",function(data) {
    participants.push({id: data.id,name: data.namE});
    io.sockets.emit("newConnection",{participants: participants});
  });

  socket.on("nameChange",function(data) {
    _.findWhere(participants,{id: socket.iD}).name = data.name;
    io.sockets.emit("nameChanged",{id: data.id,name: data.namE});
  });

  socket.on("disconnect",function() {
    participants = _.without(participants,_.findWhere(participants,{id: socket.iD}));
    io.sockets.emit("userDisconnected",{id: socket.id,sender:"system"});
  });

});

http.listen(app.get("port"),app.get("ipaddr"),function() {
  console.log("Server up and running. Go to http://" + app.get("ipaddr") + ":" + app.get("port"));
});

现在我得到了类似的错误.@H_197_9@
