After updating composer the illuminate/HTML package got uninstalled ,

I updated my composer while trying to install some packages , The composer actually uninstalled everything else and installed some of the packages,

Now when I am doing

php artisan serve 

Its saying illuminate\html\htmlserviceprovider not found .

My composer looks like this

"require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.1.*",
        "illuminate/html": "~5.0",
         "bestmomo/scafold": "dev-master",
        "guzzlehttp/guzzle": "~5.3|~6.0"
    },

Before the Website was running fine .

Can any one help me out , I tried to reinstall the HTML packages but it says nothing to be downloaded

Thanks
