Mcrypt PHP extension required on Mac OS X

Question

I keep getting this error

Mcrypt PHP extension required

at the bottom after I run a composer update :

Since I am using Mac, I have tried running :

brew search mcrypt brew install php56-mcrypt

I still get the same error message.

Sure that the mcrypt extension is not already installed, but only not activated yet in the php configuration? – Sextans

I'm not sure if the installation went through because I still get the error "Mcrypt PHP extension required." in the bottom after running composer update. – Prosperous

Well, look into the place in your file system where the extensions are installed... – Sextans

It is best not to use mcrypt, it has been abandonware for nearly a decade now. It has therefore been deprecated and will be removed from the core and into PECL in PHP 7.2. It does not support standard PKCS#7 (née PKCS#5) padding, only non-standard null padding that can't even be used with binary data. mcrypt has many outstanding bugs dating back to 2003. Instead consider using defuse or RNCryptor, they provide a complete solution, are being maintained and is correct. – Breaux

I solved this by running the following commands

brew update
brew upgrade
brew tap homebrew/dupes
brew tap josegonzalez/homebrew-php
brew install php54-mcrypt
php --version // To Test your php 
sudo composer update

No more Mcrypt warning !!

brew install homebrew/php/php55-mcrypt will do too – Progestational

Yeah as @BingHan said it will do it, just pick the good php version and your are good! – Jevons

Answer 2

After update brew:

brew update
brew upgrade
brew tap homebrew/dupes
brew tap josegonzalez/homebrew-php

If you have installed php5.6 (or higher), you can use the following command to find out what versions are available in brew:

$ brew search mcrypt
homebrew/php/php53-mcrypt     homebrew/php/php55-mcrypt         homebrew/php/php70-mcrypt     mcrypt
homebrew/php/php54-mcrypt     homebrew/php/php56-mcrypt     homebrew/php/php71-mcrypt

In my case, I am using php7.0:

$ brew install php70-mcrypt

brew search mcrypt is important because it will most likely return what you need. In my case (I assume they have consolidated the versioning) I got "libtomcrypt", "mcrypt", "scrypt", "ccrypt", and "bycrypt" on my search results. I then just ran brew install mcrypt and all was resolved. So great answer @Wakashan – Aldrich

Answer 3

On macOS High Sierra I did this steps:

1- Search the package:

brew search mcrypt

Result:

==> Searching local taps... homebrew/php/php71-mcrypt mcrypt homebrew/php/php53-mcrypt
homebrew/php/php54-mcrypt homebrew/php/php55-mcrypt homebrew/php/php56-mcrypt homebrew/php/php70-mcrypt libtomcrypt

2- Search my php version to know what can I need to install:

php --version

Result:

PHP 7.1.7 (cli) (built: Jul 15 2017 18:08:09) ( NTS ) Copyright (c) 1997-2017 The PHP Group Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies

3- Install the correct package, for me was 7.1.7 => homebrew/php/php71-mcrypt

brew install homebrew/php/php71-mcrypt

4- Find the find "mcrypt.so" extension file

find /usr/ -type f -name "mcrypt.so"

Result:

find: /usr//local/Cellar/php71-mcrypt/7.1.13_19/mcrypt.so

5- Search the php.ini

php -i | grep 'Configuration File'

Result (if exist):

Configuration File (php.ini) Path => /etc Loaded Configuration File => /etc/php.ini

6- Add the next line at the end on /etc/php.ini (see the last step your correct path) the extension mcrypt.so

 extension=/usr/local/Cellar/php71-mcrypt/7.1.13_19/mcrypt.so

Finish, you can now execute your command.

I am using XAMPP, it is not working here. Any other way? – Astyanax

I like watching this step. – Toting

Answer 4

You'll need to add the line

 extension=mcrypt.so

In your phi.ini file responsible for the CLI PHP version. To find where it is, run:

php -i | grep 'Configuration File'

Curculio

I already have it in my php.ini I checked it. Any other suggestions ? – Prosperous

When I run php -i | grep 'Configuration File' I see this : Configuration File (php.ini) Path => /etc Loaded Configuration File => (none) – Prosperous

Try this: run find /usr/lib/php/extensions -type f -name "mcrypt.so" this should give you the path where the extension is located. Then, add the directive extension_dir=/usr/lib/php./....../mcrypt.so before the extension=mcrypt.so of your php.ini – Curculio

When I run find /usr/lib/php/extensions -type f -name "mcrypt.so" I don't have anything as my outcomes. – Prosperous

@ihue did you ever find a solution? – Congenial

Answer 5

In use XAMPP on my Mac, so I had to install php and then compile mcrypt using pecl, after that I copied mcrypt.so to XAMPP.

The actual list of available releases is: http://pecl.php.net/package/mcrypt

The commands was:

echo Install php...
brew install php
/usr/local/opt/php/bin/php -v

echo Correction of "error Connection to `ssl://pecl.php.net:443' failed"...
wget http://curl.haxx.se/ca/cacert.pem
sudo cp cacert.pem /private/etc/ssl/cert.pem
sudo mv cacert.pem /Applications/XAMPP/xamppfiles/share/openssl/cert.pem
/usr/local/opt/php/bin/pecl list-all

echo Compile and Install mcrypt.so...
sudo /usr/local/opt/php/bin/pecl install mcrypt-1.0.1

The last message of build process of pecl was:

Build process completed successfully
Installing '/usr/local/Cellar/php/7.2.7/pecl/20170718/mcrypt.so'
install ok: channel://pecl.php.net/mcrypt-1.0.1
Extension mcrypt enabled in php.ini

Based on path of build process I copied the compiled mcrypt.so to XAMPP and enable the extension on php.ini:

sudo cp /usr/local/Cellar/php/7.2.7/pecl/20170718/mcrypt.so /Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20170718/mcrypt.so 
echo 'extension=mcrypt.so' >> /Applications/XAMPP/xamppfiles/etc/php.ini

Check if it works:

/Applications/XAMPP/bin/php -i | grep "mcrypt"

The result have to be:

mcrypt
mcrypt support => enabled
mcrypt_filter support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value

Remember to restart Apache to see it working using browser.

Maybe it helps someone and I win one thumbs up. Thanks

if you using brew try this :

1.Unistall existing php then Install shivammathur/php

add shivammathur php

brew tap shivammathur/php

change php version with you needed (5.6 or 7.2 or 7.4 or 8.1 or next version)

brew install shivammathur/php/[email protected]

2.Install shivammathur/extensions it s will add extension to php then

brew tap shivammathur/extensions

brew install shivammathur/extensions/[email protected]

then you install mcrypt with same version as php version

brew install [email protected]

then restart httpd

brew services restart httpd
