I’m a layman on the subject, someone knows how to solve ?

php magento xampp

  • Are you trying to install in Ubuntu ?

  • You need to insert mcypt into the local server http://php.net/manual/en/mcrypt.setup.php

    @Erloncharles I think the problem is the version of PHP, in PHP7.2 this was removed for good, since it was an obsolete module for some time.

  • @Guilhermenascimentop. he didn’t mention the php version he’s using, there’s no way to guess he’s using a recent or old version. But by error message the problem is the lack of this module.

  • @Erloncharles is that when it comes exclusively to XAMPP, they do not use old versions of PHP for years, so I assumed the problem was because php7 ;)

The module mcrypt was already obsolete since PHP 5.5 (at least several of its functions) and was removed once and for all in PHP7.2, according to the link http://php.net/manual/en/intro.mcrypt.php:

Warning This Feature was DEPRECATED in PHP 7.1.0, and REMOVED in PHP 7.2.0.

Alternatives to this Feature include:

This message is coming to you because probably the version you’re using Magento is very old or else you are using PHP7 on your local machine.

There is no way to enable this module in PHP7, as it simply does not exist anymore for PHP7 and PHP5 if it is Windows only by downloading the .dll from some external source, however what I recommend is that you update Magento!

If it is Ubuntu and PHP 5 you can try to install via repository (it may be available) through the command:

 sudo apt-get install php5-mcrypt

Afterward:

sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/mcrypt.ini

Then enable the extension using php5enmod and restart Apache:

sudo php5enmod mcrypt
sudo service apache2 reload

If something fails, especially in apt-get is probably because Ubuntu has already removed this module from the repositories.
