Answer 1

I am on a Mac OS X Yosemite using Terminal, and I fix this error

the requested PHP extension mcrypt is missing from your system

by running the following commands :

brew update
brew upgrade
brew tap homebrew/dupes
brew tap josegonzalez/homebrew-php
brew install php54-mcrypt

Answer 2

Try this:

sudo apt-get install php5-mcrypt
sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available
sudo php5enmod mcrypt 
sudo service apache2 restart

Answer 3

For those using a LEMP stack (nginx & php5-fpm), this is the solution

apt-get install php5-mcrypt
php5enmod mcrypt
service php5-fpm restart
service nginx restart

(run each with sudo, naturally)

Answer 4

I've followed the exact tutorial with OP on digital ocean. The only steps that missing is to

sudo php5enmod mcrypt
sudo service apache2 restart 

and the error gone after restarting the apache service

Answer 5

Try this:

sudo apt-get install mcrypt php5-mcrypt; php5enmod mcrypt; service apache2 restart

Answer 6

I just stuffed a symbolic link into the Apache portion of php configuration. Platform: Xubuntu 14.04 LTS.

Details:

1. cd /etc/php5/apache2/conf.d
2. sudo ln -s ../../mods-available/mcrypt.ini 20-mcrypt.ini
3. ls -l to see if the new link is there
4. sudo apache2ctl restart

HTH.
