ERROR: Couldn't parse 'composer.lock'; it must be a valid lock file generated by Composer

I'm trying to deploy a simple app to Heroku, but keep getting this error message:

Alastairs-MacBook-Air:php-getting-started alastair$ git push heroku master

error: failed to push some refs to 'https://git.heroku.com/arcane-peak-94383.git'

It's this tutorial.

I've ran composer update multiple times, add/committed the change, and reinstalled composer. All with no luck. The composer.lock file was generated by Composer, as I've regenerated it by running composer update.

Here's my composer.json file:

{
 "require" : {
"silex/silex": "^1.3",
"monolog/monolog": "^1.4",
"twig/twig": "^1.8",
"symfony/twig-bridge": "^2",
"alrik11es/cowsayphp": "^1.0"
  },
  "require-dev": {
"heroku/heroku-buildpack-php": "*"
 }
}

I know this is a simple solution, but I have been trying to resolve for a couple of hours now. Thanks in advance.

The answer from SO that should do it:

Seems that Heroku supports only latest versions of Composer.

composer self-update and further composer update (+ git add, + git commit) should fix the issue.
