Installing with Composer - php extensions: ext-mcrypt * and ext-intl * missing from your system on XAMPP

Question

I've been trying to install Magento 2. I did load everything and with the last commands "composer update" or "composer install" I'm having problem.

Problem 1
    - The requested PHP extension ext-mcrypt * is missing from your system.
  Problem 2
    - The requested PHP extension ext-intl * is missing from your system.

The thing is I'm not a pro Mac user or anything so it's very complicated for me to understand what I need to do to resolve this. I saw a topic here at stackoverflow with the same problem but in that case they were using MAMP. I'm using XAMPP. They were telling to override PHP with MAMP's PHP with the .bash_profile file. I tried the same - didn't quite understand what I was doing.

So please, can anyone help me with solving ext-mcrypt and ext-intl stuff? I don't even know how to find out if they are missin or not.

Thanks!

Here's what in place of mcrypt

[mcrypt]
; For more information about mcrypt settings see http://php.net/mcrypt-module-open

; Directory where to load mcrypt algorithms
; Default: Compiled in into libmcrypt (usually /usr/local/lib/libmcrypt)
;mcrypt.algorithms_dir=

; Directory where to load mcrypt modes
; Default: Compiled in into libmcrypt (usually /usr/local/lib/libmcrypt)
;mcrypt.modes_dir=

FINAL NOTES:

I marked answer as correct as it resolved my issue with mcrypt with the link from Laravel requires the Mcrypt PHP extension next I had issue with ext-intl and to resolve this please follow these links: http://codingexplained.com/operating-systems/mac/installing-php-intl-extension-os-x-mavericks and Php-intl installation on XAMPP

I did write an article about these issues and solution. hopefully this helps too!

Answer 1

Have a look at this answer Laravel requires the Mcrypt PHP extension and the following one .

If mcrypt is not enabled open your php.ini (see my first answer link above how to find it) and search for

;extension=php_mcrypt.so

then remove the ; from the beginning of that line. Same procedure for the other extension.

Answer 2

On linux I:

sudo apt-get install php7.0-mcrypt ;
sudo apt-get install php7.0-intl

Answer 3

Following things you can check -

• Apache Version: 2.2 or 2.4 and Enable: mod_rewrite.mod_rewrite enables the server to perform URL rewriting.
• PHP: 5.4.x where x = 11 or later 5.5.x and
• Enable PHP Extension: PDO/MySQL,mbstring, mcrypt, mhash, simplexml, curl, gd2, ImageMagick 6.3.7 (or later) or both soap and
• add xdebug.max_nesting_level=50000; at php.ini
• MySQL Version : 5.6.x and upper

Hope it will help.

Answer 4

If you are using Linux and PHP 7.0 you would use something like this:

yum install php70u-intl

I have PHP version 70u in the above example. Bu this will provide "ext-intl".
