Deploying node.js application to Heroku

Question

Using the dead simple tutorial on Heroku's website and when I run git push heroku master I receive the following error:

       Using Node.js version: 0.4.7
       Using npm version: 1.0.106
-----> Fetching Node.js binaries
-----> Vendoring node into slug
-----> Installing dependencies with npm

       npm not ok
 !     Failed to install --production dependencies with npm
 !     Heroku push rejected, failed to compile Node.js app

My package.json is:

{
  "name": "node-example",
  "version": "0.0.1",
  "dependencies": {
    "express": "2.2.0"
  }
}

There's absolutely nothing wrong with my JSON, which I got from their tutorial, because when I run it locally, it works great. Why am I getting this error?

Looks perfectly valid and validates for me - are you sure you've commited any changes to the file and pushed to git so that the correct file is being pushed to Heroku? — John Beynon

I committed and pushed all of my changes but it still wouldn't work. I simply started over with the same tutorial and everything worked. Don't know what I screwed up the first time but the second time it worked great. — Spencer Carnage

I get the feeling this would have had the answer

 npm ERR! Additional logging details can be found in:
       npm ERR!     /tmp/build_17bicinzz6vv0/npm-debug.log

Try adding the whole content in package.json as provided by Heroku tutorial.... I also got the same error, it was removed by adding engines.

`{
    "name": "app-name",
    "version": "0.0.1",
    "private": true,
    "dependencies": {
      "express": "~2.5.8",
      "ejs": "~0.7.1",
      "socket.io": "~0.9.6"
  },
  "engines": {
    "node": "0.6.x"
  }
}`
