How to fix–mcrypt PHP extension required in Laravel on Mac OS X (No MAMP)

Laravel PHP Web framework requires certain libraries to function properly. One of these libraries is the MCrypt and the Php-mcrypt (bridge between MCrypt and PHP). However, there is a good chance so you'll run into issues while running Laravel if these libraries and the extensions is not properly installed.

When I got started with setting-Laravel on a Mac OS X maverics Development Machine, I-ran into this error which said:m Crypt PHP extension required. This can is fixed easily-in, ways either by installing Php54-mcrypt or the php55-mcrypt extension using Homewbrew for Mac or my manually compiling the php-mcrypt extension. The development machine have the pre-installed PHP on OS X Maverics and isn't the one from a third party package installer Li Ke MAMP.

Step 1:install mcrypt for Mac OS X maverics using homebrew-this command:

sudo brew install MCrypt

Just in case you get a brew error while running this command, this is the cowardly refusing to sudo error from brew, Fix it and try the above command again.

Step 2:install php-mcrypt Extension using brew (based on your PHP version PHP 5.4 or PHP 5.5:

sudo brew install Php55-mcrypt

Or

sudo brew install Php54-mcrypt

If You get errors like brew no available formula and then you'll have to build the mcrypt extension for PHP manually which is a really easy step.

After you do with above steps, you should now no longer see the Mcrypt PHP extension required error and is all Set to start your Laravel development.
