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!

I hope this one can help someone
I have tried to install mcrypt with php7.1 but I got a warning "pecl/mcrypt requires PHP (version >= 7.2.0, version <= 7.3.0, excluded versions: 7.3.0)"
so I changed to php version 7.2 and run sudo pecl install mcrypt-1.0.1
after that, I switch to PHP 7.1 and it works
I'm using mac os v10.14 and apache environment

If this can help someone... I did a lot of clean-up to get it to work... Now, first thing is start with a clean brew... that is,
brew doctor
is clean... all previous PHP are uninstalled and the actual directories cleaned up... then re-install 7.1 clean... then a simple
brew install mcrypt
will actually do the work and link the right pecl directory linked... That was a lot of work... but a great opportunity to clean up my mac... lol

I tried to do sudo pecl install mcrypt which tries to install mcrypt-1.0.2, but it fails on High Sierra on PHP 7.2. Using exactly sudo pecl install mcrypt-1.0.1 it did the trick.

OS Mojave works perfectly

brew install mcrypt
followed by
pecl install mcrypt-1.0.1

You may need to alter your php.ini file after this.

For PHP 7.3, I installed mcrypt-1.0.2 as it supports PHP>=7.2 and PHP<=7.4
brew install mcrypt
pecl install mcrypt-1.0.2

I use Mojave and PHP 7.3. This works for me.
I didn't need to edit my php.ini, pecl did it automatically

php 7.2

brew install mcrypt
pecl install mcrypt-1.0.1

Pecl installation failed. I see, that my directory links was broken.

in /usr/local/Cellar/[email protected]/7.2.15/share/[email protected]/pear/System.php:294 I so that it try to create /usr/local/Cellar/[email protected]/7.2.15/pecl . In the fact it's a broken link to /usr/local/lib/php/pecl. That directory was not created. If you have something like thiis, you need to create another link, like:

cd /usr/local/lib/php && ln -s 20170718 pecl

for php 7.2 on High Sierra, similar to above, this worked for me:

brew install mcrypt
$(brew --prefix [email protected])/bin/pecl install mcrypt

(you might need --force on the pecl install)

If you use Laravel Valet, give a valet restart command after installing mcrypt so the system should recognise the lib.

Hi there! I solved this problem in Mac using Mojave. I had a Laravel mcrypt dependency. I did this:

  1. brew install httpd
  2. brew install [email protected]
  3. edit the http.conf (after installation it will tell you where's localted) and add that php version.
  4. In my case, I run it using the port 8080, so I configure it to be http://localhost:8080 that way I have both running (the default).
    mcrypt will be included, however, I did too many changes to you may also need to install mcrypt by doing this:
  • Also just in case (because I did too many things)
    If you still don't have mcrypt available, then:
  1. Install pecl
  2. sudo pecl install mcrypt-1.0.1

restart your brew apache using "sudo apachectl restart" and done!

pecl/mcrypt requires PHP (version >= 7.2.0, version <= 7.3.0, excluded versions: 7.3.0), installed version is 5.6.40
No valid packages found
install failed

above is my issue, it seems it no longer exist.

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/[email protected]

Happy coding!

I tried this for [email protected], 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:

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/[email protected]" in the list)
3. brew install shivammathur/extensions/[email protected]

you will fine mcrypt.so in the "/usr/local/[email protected]/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
