按照 12devs of Xmas 教程创建我的第一个 Node.js 应用程序(http://12devsofxmas.co.uk/post/2012-12-28-day-3-realtime-collaborative-drawing-with-nodejs)我'我现在尝试按照 Rob Dodson 的教程通过 Heroku 部署它(http://robdodson.me/blog/2012/06/04/deploying-your-first-node-dot-js-and-socket-dot-io-应用程序到heroku/)
但是,在提交到 github 后,当我尝试推送到 Heroku 时,我得到以下错误输出:

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"
}
}
对不起 - 我对这种开发完全陌生,在学校期间主要使用 Java 工作,但我很想学习。我认为问题出在 express 上,但我不确定“将其移开,然后重试”是什么意思。
