Install Mcrypt on Mac

Recently I setup Laravel enviroment on my Macbook, when I create project or run php artisan, it always prompts `Mcrypt PHP extension required.` error for me. Becuase I am using vagrant homestead for Laravel development, I can `homestead ssh` to run commands, but I think it’s better and convenience for me to install Mcrypt on my local enviroment. Then I did some reseach, and setup Mcrypt with mac native PHP.

There are three ways I found:

  • Manuall complie Mcrypt from souce and install
  • Using Homebrew to install
  • Using MAMP Mcrypt

For my requirement, I think homebrew is the best way for me.

First, need install `autoconf` which is needed when homebrew compling Mcrypt

brew install autoconf

Then need Homebrew `dupes`, `versions`, and `homebrew-php` tap

brew tap homebrew/dupes
brew tap homebrew/versions
brew tap homebrew/homebrew-php

After that, you can install `php55` or `php56`

brew install php55


brew install php56

Install PHP Mcrypt

brew install php55-mcrypt


brew install php56-mcrypt

At last, need add mcrypt extension into `/etc/php.ini`. You can find path using `brew info php55-mcrypt`, eg.

extension= /usr/local/Cellar/php55-mcrypt/5.5.20/
