git push heroku master fails with parse error - which file?

Question

I'm getting a parse error when I do a git push heroku master. Heroku tells me which line and column is causing the parse error, but not which file. How do I find out which file heroku is having trouble parsing? Please advise.

----- package.json -----

{
  "name": "mean",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node server.js"
  },
  "dependencies": {
    "mongoose": "3.8.7",
    "express": "3.4.8",
    "jade": "*",
    "stylus": "*"
  },
  "engines": {
    "node": "0.10.x",
    "npm": "1.4.x"
  }
}

----- output -----

Answer 1

Happened to me too, it was the comma I missed in the .json file.

You probably didn't put that comma in line 13 right away, and you commited

  },

Commit again and then push to Heroku.

Answer 2

I just got the same exact error. In my case the problem was in the package.json file because I missed the comma after I manually added "engines" to it:

{
    "engines": {
        "node": "0.10.x"
    },  <-- missed this comma here

    "name": "heroku",...
