Yah I’ve faced this problem several times while installing laravel with composer, I’m using Ubuntu 13.10. its very weird problem really. I got this error message when I entered this command.
[php]php artisan serve[/php]
The error message is like this
But the point is its already installed in my system.
You have to enter below command to solve this
sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available
sudo php5enmod mcrypt
sudo service apache2 restart
You are done I think now run the command again, I’m also learning laravel 😛
Ow! Robert gave me the solution 🙂
