I was able to resolve that through updating the composer.jason file by replacing `"fabpot/php-cs-fixer": "~1.2"` with `"friendsofphp/php-cs-fixer": "~2.0"`

and on the composer.lock replacing  `"fabpot/php-cs-fixer": "0.4.0"` with `"friendsofphp/php-cs-fixer": "0.4.0"` and replacing  `"fabpot/php-cs-fixer": "1.7.*"` with `"friendsofphp/php-cs-fixer": "2.0.*"`
