Answer 4

I had the same problem with PHP 5.5.14 running on Mac OS X Yosemite. I was trying to install Laravel 5.0. And when I tried to create a new project I got an error like below (even when I tried to start the laravel server with php artisan serve

Alejandros-MacBook-Pro:Documents Lexynux$ laravel new blog
Crafting application...

So I just added the line below at the end of my php.ini file with the nano editor:

extension=mcrypt.so
sudo nano /etc/php.ini

Finally just restart the Terminal and restart the laravel app server with

php artisan serve

And it works fine!

Answer 5

Try this code:

ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/apache2/conf.d/20-mcrypt.ini
service apache2 restart

Answer 6

just found on php.net

Note, for Ubuntu, simply installing php5-mcrypt did not get mcrypt to work. You need to execute the following commands as root to enable it:

apt-get install php5-mcrypt
mv -i /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
php5enmod mcrypt
service apache2 restart
