Heroku bash: node: command not found

Question

Have someone out there got this error when starting a node app on heroku before?

2012-10-17T20:28:52+00:00 heroku[web.1]: Starting process with command `node app.js`
2012-10-17T20:28:53+00:00 app[web.1]: bash: node: command not found

It seems like the Heroku app are missing node.

The app starts just fine locally. Both foreman start and node app.js.

{
    "name": "app-name",
    "description": "some desc",
    "version": "0.0.1",
    "private": true,
    "engines": {
        "node": "0.8.12",
        "npm":  "1.1.49"
    },
    "dependencies": {
        "express" : "2.5.9",
        "mongoose" : ">=2.6.0",
        "colibri" : "*",
        "jade": ">= 0.0.1"
    }
}

Answer 1

What fixed it for me was to add the heroku/nodejs buildpack in heroku settings.

Old question, but, try adding an engines section to your package.json:

"engines": {
    "node": ">= 6.9.4",
    "npm": ">= 4.4.0"
  }

Answer 3

First, ensure that your application is using the heroku/nodejs buildpack:

$ heroku buildpacks

1. heroku/nodejs

If this is not the case then change your builpack to nodejs using :

$ heroku buildpacks:set heroku/nodejs

Answer 4

Heroku recognizes an app as Node.js by the existence of a package.json. Even if your app has no dependencies, you should still create a package.json that declares a name, version, and empty dependencies in order that it appear as a Node app.
