Install Mcrypt on macOS

Install-Mcrypt.md

Setup php-mcrypt on macOS (and versions of Mac OS X)

These steps should have been mentioned in the prerequisites of the Laravel Installation Guide, since I'm surely not the only person trying to get Laravel running on macOS.

Install

Install Mcrypt using Homebrew and PECL (comes with PHP)

# PHP 7.3
$ brew install mcrypt
$ pecl install mcrypt-1.0.3

Find your php.ini:

$ php -i | grep "Loaded Configuration File"
Loaded Configuration File => /usr/local/etc/php/7.3/php.ini

Add this line to your php.ini:

extension=/usr/local/Cellar/php/7.3.x/pecl/20180731/mcrypt.so

Historic Answer

Install Mcrypt using Homebrew

# PHP 7
$ brew install php70-mcrypt

# PHP 5
$ brew install php56-mcrypt --without-homebrew-php

Add this line to /private/etc/php.ini:

# PHP 7
extension="/usr/local/Cellar/php70-mcrypt/7.0.x/mcrypt.so"

# PHP 5
extension="/usr/local/Cellar/php56-mcrypt/5.6.x/mcrypt.so"

You are ready to go!

Try the following steps found here. I setup my PHP using brew tap shivammathur/php.

My PHP version 7.0 however in the link you can install other PHP versions.

  1. brew tap shivammathur/extensions
  2. brew install shivammathur/extensions/mcrypt@7.0

Happy coding!

I tried this for php@5.6, but it's not clear what is the next step to get mcrypt working? I tried pecl install mcrypt <5.6 mcrypt dir> but didn't work? See below:

pecl/mcrypt requires PHP (version >= 7.2.0, version <= 8.2.0, excluded versions: 8.2.0), installed version is 5.6.40

So, I temporarily switched to using php 7.4 and tried running again and...

pecl/mcrypt is already installed and is the same as the released version 1.0.5
install failed

Has anyone got this working recently for 5.6?

hi,bro
I have the same problem, and i resolved it...

1.brew tap shivammathur/extensions
2. brew search mcrypt(it will show "shivammathur/extensions/mcrypt@5.6" in the list)
3. brew install shivammathur/extensions/mcrypt@5.6

you will fine mcrypt.so in the "/usr/local/mcrypt@5.6/5.6.40"

Support for PHP 7.x runs out in just a few days, you can't be serious about still using 5.x
