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.

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

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".

Answer 3

On linux I:

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

Answer 4

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
