Magento 2 on Mamp pro requires ext-mcrypt

Question

I'm trying to install Magento 2 on my MAMP PRO but I receive this error from composer:

*Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - magento/framework 100.0.4 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.
    - magento/framework 100.0.4 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.
    - Installation request for magento/framework 100.0.4 -> satisfiable by magento/framework[100.0.4].*

But mcrypt is install in my MAMP:

I tried adding the php version to .bash_profile file but it didn't resolve:

export MAMP_PHP=/Applications/MAMP/bin/php/php5.5.10/bin
export PATH="$MAMP_PHP:$PATH"

I try running php -i | grep mcrypt this is the result: ~/Sites/magento2 $ php -i | grep mcrypt

Answer 1

On Mac, running MAMP: You need to find the php.ini file for the version of php you are running and replace the extension_dir line as below. (making sure to replace "php5.6.10" with your version and "no-debug-non-zts-20131226" with the name of the folder inside extensions.)

php.ini file usually located at: mamp/php/your-php-version/conf

extension_dir = "/Applications/MAMP/bin/php/php5.6.10/lib/php/extensions/no-debug-non-zts-20131226/"
