麻煩通過Heroku的

第一個Node應用程序部署已經跟着聖誕教程12devs創建我的第一個Node.js的應用程序（http://12devsofxmas.co.uk/post/2012-12-28-day-3-realtime-collaborative-drawing-with-nodejs）現在我試圖跟隨羅布多德森的教程通過的Heroku（http://robdodson.me/blog/2012/06/04/deploying-your-first-node-dot-js-and-socket-dot-io-app-to-heroku/）麻煩通過Heroku的

進行部署

然而，承諾github上，之後當我嘗試推到Heroku的，我碰到下面的錯誤輸出：

-----> Installing dependencies with npm

我的package.json文件如下：

{ 
    "name": "Draw", 
    "version": "0.0.1", 
    "private": true, 
    "dependencies": { 
     "express": "~2.x", 
     "socket.io": "~0.9.x" 
    }, 
    "engines": { 
     "node": "0.6.x", 
     "npm": "1.1.x" 
    } 
}

對不起 - 我完全陌生的這種發展，已經在Java中大部分的工作，而在學校，但我渴望學習。我認爲問題是某種方式表達，但我不知道這是什麼意思是「將其移開，然後再試一次。」
