Laravel 4 - Error while running `composer install`

Question

The problem:

I have installed Composer and followed the Quick start guide in the Laravel 4 documentation.

I get the following error when I run composer

Answer 1

It says:

MCrypt PHP extension required

So it looks like you're missing the Mcrypt extension, which is required by Laravel (actually, I think it's used only by the Authentication class for password handling, not for the rest of the components of the framework).

I haven't got a Mac, but the command to install it should be something like this, using Homebrew

brew tap josegonzalez/php
brew install mcrypt php54-mcrypt
