composer update (php artisan clear-compiled) error

This is what is happening when I run composer update in my root directory:

Halichu@HALICHU-PC /c/Source/ventrac (master)
$ composer update
> php artisan clear-compiled
"forms"
Script php artisan clear-compiled handling the pre-update-cmd event returned wit
h an error



  [RuntimeException]
  Error Output:

I don't understand this error. This is what my composer looks like:

        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}

I even got rid of the packages I'm developing and tried to run it again, but it's still outputting this error.. I don't get why it's echoing "forms" out into it.

Thanks for any help.
