Laravel Compile issue

While compiling laravel i faced this error

  Problem 1
    - Installation request for laravel/framework v5.0.16 -> satisfiable by laravel/framework[v5.0.16].
    - laravel/framework v5.0.16 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.

Solution :

 sudo php5enmod mcrypt
 sudo service apache2 restart
