Question

我即将完成使用 socket.io 的 Ionic2 应用程序。我用一个终端中的ionic serve（客户端）和另一个终端上的node index.js（服务器端）运行（本地）我的应用程序。（index.js文件位于我的ionic2项目文件夹中）。现在我想用Heroku试试这个。

这些是我的服务器端文件：

我的index.js文件如下所示：

var io = require('socket.io'),
    http = require('http'),
    server = http.createServer(),
    io = io.listen(server);
...
...
my real code here
...
...
server.listen(process.env.PORT || 3000, function(){
  console.log('Server started, listening on' + process.env.PORT);
});

与index.js一起创建（npm init）包json，如下所示：

{
  "name": "myApplication",
  "version": "0.2.5",
  "description": "just a server",
  "engines": {
    "node": "4.2.6"
  },
  "main": "index.js",
  "scripts": {
    "start": "node index.js"
  },
  "dependencies": {
    "ejs": "2.4.1",
    "express": "4.13.3",
    "socket.io": "^1.5.0"
  },
  "repository": {
    "type": "git",
    "url": "https://github.com/xxxxxxxxx"
  },
  "keywords": [
    "node",
    "heroku",
    "express"
  ],
  "license": "MIT"
}

Procfile内容是：web: node index.js

虽然app.json持有这个：

{
  "name": "MyAppServer",
  "description": "",
  "repository": "https://github.com/xxxxxxxx",
  "logo": "http://node-js-sample.herokuapp.com/node.svg",
  "keywords": ["node", "express", "static"],
  "image": "heroku/nodejs"
}

在将所有这些内容推送到github repo之前我已经完成了npm install所以我得到了node_modules个文件夹。所以我把所有东西都推到了github仓库，然后是heroku login，heroku create。最后git push heroku master返回了我Build succeeded但现在，当我heroku open时，我看到一个页面显示应用程序错误。

这些是我heroku logs时收到的警告：
