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：

web: node server.js

这是我的package.json

{
  "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

$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

$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？

编辑：这是一些日志

EDI：server.js

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", function(request, 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.

如果没有创建服务器的Node代码,我无法确定,但是从日志中看起来你没有正在监听正确的端口.

Heroku为您的应用程序分配一个应用程序必须侦听的端口(设置为“PORT”环境变量).如果你没有在60s内连接到这个端口,它将会杀死你的应用程序,这似乎正在发生的事情.

更新：事实上,基于你的web.1日志条目,看起来你正试图在端口8080上侦听.我认为这不太可能是Heroku提供的端口.您可以从process.env.PORT获取Heroku提供的端口,然后听取它.
