Node.Js and Socket.IO application on Heroku

Question

I am having this error message when I try to deploy my application on Heroku. Any suggestions? I can easily deploy my app on localhost but it doesn't work on Heroku.

My Package.JSON is:

{
    "name":"tryout",
    "version":"0.0.1",
    "private":true,
    "scripts":{
        "start":"node app"
    },
    "dependencies":{
        "express":"3.0.0rc3",
        "jade":"*",
        "passport":">= 0.1.11",
        "passport-local":">= 0.1.3",
        "underscore":">= 1.3.3",
        "socket.io":">= 0.9.6",
        "node-uuid":">= 1.3.3",
        "mongoose":">= 3.0.2",
        "bcrypt":">= 0.7.1"
    },
    "engines": {
        "node": "0.8.x",
        "npm": "1.1.x"
    }
}

PS: I don't use hiredis at all.

Input command is: git push heroku master

Answer 1

It seems hiredis is indirectly needed by express, which you have a release candidate version, which might be the problem. Try to change express to:

"express":"3.x"

Also, make sure you don't commit the node_modules directory to your git repo. Add it to .gitignore!
