Laravel requires the Mcrypt PHP extension

Question

I am trying to use the migrate function in Laravel 4 on OSX. However, I am getting the following error:

Laravel requires the Mcrypt PHP extension.

As far as I understand, it's already enabled (see the image below).

What is wrong, and how can I fix it?

Answer 1

This solution is for PHP 7.4.X on WAMP in Windows 10 (It will work for others versions if you manage to find the php_mcrypt.dll file for PHP version that you need).

• Download dll here : https://windows.php.net/downloads/pecl/releases/mcrypt/1.0.3/php_mcrypt-1.0.3-7.4-ts-vc15-x64.zip

• unzip and paste php_mcrypt.dll to **C:\wamp64\bin\php\php7.4.0\ext**

• Include following lines in C:\wamp64\bin\php\php7.4.0\php.ini or C:\wamp64\bin\apache\apache2.4.51\bin\php.ini:

   [mcrypt]
   extension=php_mcrypt.dll
   OR
   extension=mcrypt
  

• Restart WAMP server

For other PHP versions you may find the php_mcrypt.dll file in https://pecl.php.net/package/mcrypt or in php windows binaries file: in PHP windows binaries files in ext/ folder https://windows.php.net/downloads/releases/

Answer 2

For those who still come here today:

Laravel does not need mcrypt extension anymore. mcrypt is obsolete, the last update to libmcrypt was in 2007. Laravel 4.2 is obsolete too and has no more support. The best (=secure) solution is to update to Laravel 9.x+ (Laravel 8.x is still okay. But if you are upgrading, then upgrade to the latest version).

Mcrypt was removed from Laravel in June 2015: https://github.com/laravel/framework/pull/9041

Answer 3

in Ubuntu 14.04

sudo apt-get install php5-mcrypt
sudo php5enmod mcrypt

Ubuntu 16.04

sudo apt-get install php-mcrypt
sudo phpenmod mcrypt

Ubuntu 18.04

sudo apt install php7.0-mcrypt
sudo phpenmod mcrypt

or

sudo apt install php7.2-mcrypt
sudo phpenmod mcrypt

Answer 4

sudo php install mcrypt

sudo php5enmod mcrypt

Answer 5

Just for yumers,

yum install php-mcrypt
service httpd restart
chown -R apache:apache apppath

Maybe you need install remi repo

Answer 6

My OS is Yosemite.

I resolve this issue, by finding configuration paths:

php --ini

Example output:

Configuration File (php.ini) Path: /usr/local/etc/php/5.5
Loaded Configuration File:         /usr/local/etc/php/5.5/php.ini
Scan for additional .ini files in: /usr/local/etc/php/5.5/conf.d
Additional .ini files parsed:      (none)

Next steps:

1. Rename or Delete php55 ini file
2. Create symlink
3. Restart Apache server

Commands:

mv /usr/local/etc/php/5.5/php.ini /usr/local/etc/php/5.5/php.ini.default
ln -s /etc/php.ini /usr/local/etc/php/5.5/php.ini
sudo apachectl restart

Then you can check your php modules via:

php -m

Answer 7

Or, use:

sudo apt-get install php5-mcrypt

not sure if this will work on standard PHP installs - I installed php 5.5.7 using the package from :

sudo add-apt-repository ppa:ondrej/php5 
sudo apt-get update

Answer 8

For ubuntu try these steps if others are not working :

1. cd ~
2. sudo apt-get remove php5-mcrypt
3. sudo apt-get install php5-mcrypt
4. sudo php5enmod mcrypt
5. sudo service apache2 restart

Hope that will help. Thanks !

Answer 9

The web enabled extensions and command line enabled extensions can differ. Run php -m in your terminal and check to see if mcrypt is listed. If it's not then check where the command line is loading your php.ini file from by running php --ini from your terminal.

In this php.ini file you can enable the extension.

OSX

I have heard of people on OSX running in to problems due to the terminal pointing to the native PHP shipped with OSX. You should instead update your bash profile to include the actual path to your PHP. Something like this (I don't actually use OSX so this might not be 100%):

export PATH=/usr/local/php5/bin:$PATH

Ubuntu

On earlier versions of Ubuntu (prior to 14.04) when you run sudo apt-get install php5-mcrypt it doesn't actually install the extension into the mods-available. You'll need to symlink it.

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

On all Ubuntu versions you'll need to enable the mod once it's installed. You can do that with php5enmod.

sudo php5enmod mcrypt
sudo service apache2 restart

NOTES

• PHP 7.1 deprecated mcrypt and 7.2 has removed the mcrypt extension entirely
• Laravel 5.1 and later removed the need for mcrypt

Answer 10

OSX with brew

$ brew install mcrypt php70-mcrypt

I am running PHP 7.0.x, so change "php70" to your version, if you are using a different version.
As stated in other answers, you can see your php version with $ php -v.

Answer 11

Do you have MAMP installed?

Use which php in the terminal to see which version of PHP you are using.

If it's not the PHP version from MAMP, you should edit or add .bash_profile in the user's home directory, that is : cd ~

In .bash_profile, add following line:

export PATH=/Applications/MAMP/bin/php/php5.4.10/bin:$PATH

---

Edited: First you should use command cd /Applications/MAMP/bin/php to check which PHP version from MAMP you are using and then replace with the PHP version above.

Then restart the terminal to see which PHP you are using now.

And it should be working now.

Answer 12

For non MAMP or XAMPP users on OSX (with homebrew installed):

brew install homebrew/php/php56-mcrypt

Cheers!

Answer 13

If you are using Z Shell, just do the following:

1. Open terminal
2. sudo nano ~/.zshrc
3. Paste this; export PATH=/Applications/MAMP/bin/php/php5.6.10/bin:$PATH
4. Save
5. Run source ~/.zshrc
6. Run which php - you should get the MAMP 5.6.10 path

5.6.10 is the version of PHP you set in your MAMP.

Answer 14

On OS X

Using MAMP

Enter the command which php in the terminal to see which version of PHP you are using. If it's not the PHP version from MAMP, the $PATH variable used by Bash will need to be updated.

First, you should use command "cd /Applications/MAMP/bin/php" to check which php version from MAMP and take note of the version (eg, php5.6.7).

Once you know the version, you should edit the ~/.bash_profile file (that is, the .bash_profile that is in your home directory) and add an export line:

    export PATH=/Applications/MAMP/bin/php/php5.6.7/bin:$PATH

Make sure that you replace php5.6.7 with the version of PHP that you have selected in MAMP.

Once the file has been saved, make sure that you close close your Terminal and open it again. Once that has been done, you will be using the PHP that ships with MAMP.

---

One way to easily find what the line should be that you need to put inside your .bash_profile is to run the following command inside your terminal:

    echo export PATH=`cat /Applications/MAMP/conf/apache/httpd.conf \
         | grep php | grep -i LoadModule | head -n1 \
         | sed -e 's/^[^\/]*\/\(.*\)\/mod.*/\/\1/'`/bin:\$PATH

Copying and pasting those three lines into your terminal will correctly output the PHP version that has been selected inside the MAMP control panel.

Using Homebrew/MacPorts

Make sure that your path contains /usr/local/bin/ (Homebrew) or /opt/local/bin (MacPorts) if you are using PHP that comes with either of these two package managers.

Checking the PHP path with MacPorts

You can find the exact location of PHP using MacPorts with the following command:

port contents php70 | grep bin/php

Note that you should replace php70 with the version of PHP that you have installed.

Check the PHP path with Homebrew-php

Homebrew-php (https://github.com/Homebrew/homebrew-php) is a tap that has various different versions of PHP.

You can find the exact location of PHP using Homebrew with the following command:

brew --prefix homebrew/php/php56

Note that you should replace php56 with the version of PHP that you have installed.

Answer 15

You need an all in one environment. You may use MAMP or XAMPP or any other tools. After installing one of these tools you will need to edit(create) your .bash_profile(Assuming that you use bash).

Or even simple and more professional you can use Laravel Homestead.

Here is a link to official documentation: http://laravel.com/docs/5.0/homestead

Also Jeffrey has a free tutorial about it: https://laracasts.com/series/laravel-5-fundamentals/episodes/2

I advice you to go with homestead because you will preinstall all of the following tools.

• Ubuntu 14.04
• PHP 5.6
• HHVM
• Nginx
• MySQL
• Postgres
• Node (With Bower, Grunt, and Gulp)
• Redis
• Memcached
• Beanstalkd
• Laravel Envoy
• Fabric + HipChat Extension

Answer 16

To those that uses XAMPP 1.7.3 and Mac

1. Go to Terminal
2. Enter which php
   • If it says /usr/bin/php, then proceed to 3.
3. Enter sudo nano ~/.bash_profile (or sudo vim ~/.bash_profile if you know how to use it)
4. Then paste this export PATH="/Applications/XAMPP/xamppfiles/bin:$PATH"
5. Ctrl+O then enter to save, then Ctrl+X to exit.
6. Type cd ~
7. type . .bash_profile
8. restart terminal.
9. Enter which php. If you did it right, it should be the same as the path in #4.

The reason for the mcrypt error is because your Mac uses its native php, you need to change it to the one xampp has.

P.S. I'd recommend using MAMP for Laravel 4 for Mac users, this issue will get resolved along with the php file info error without a sweat, and the php version of xampp is so outdated.

Answer 17

For php-fpm installations on Ubuntu 14.04, the following worked for me :

sudo apt-get install php5-mcrypt

This will create mcrypt.ini file inside /etc/php5/mods-available/

Then

sudo php5enmod mcrypt

will create a symlink in: /etc/php5/fpm/conf.d/

Just restart php-fpm services sudo service php5-fpm restart

Answer 18

Getting Laravel working on Apache

PHP version : PHP 5.5.9

Ubuntu version : 14.04

i had a working laravel project on windows. when i copied it to ubuntu server , i started getting the mcrypt error. this after a lot of hours of trial and error

getting artisan command working

(if you are having mcrypt error while using artisan command line tool)

i did a lot of trial and error so each time i run the php5enmod command before, i had error messages. but on fresh install there was no error messages. after this step i got artisan command working

sudo rm /etc/php5/mods-available/mcrypt.ini
sudo apt-get purge php5-mcrypt
sudo apt-get install mcrypt
sudo apt-get install php5-mcrypt
sudo php5enmod mcrypt

fixing the browser error

(if you are having mcrypt error in browser when accessing local laravel index page)

sudo nano /etc/php5/apache2/php.ini

add the following line under the dynamically compiled extensions section of php ini

extension=mcrypt.so

restart the apache server , purge the laravel cache and everything working

Answer 19

In Ubuntu (PHP-FPM,Nginx)

sudo apt-get install php5-mcrypt

After installing php5-mcrypt

you have to make a symlink to ini files in mods-available:

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

enable:

sudo php5enmod mcrypt

restart php5-fpm:

sudo service php5-fpm restart

Answer 20

Using Ubuntu, just

sudo php5enmod mcrypt

did the trick for me. You don't need to restart Apache since you need to use PHP just from the CLI.

Answer 21

This solved it for me on my Linux Mint local enviroment https://askubuntu.com/questions/350942/cannot-get-mcrypt-for-php5

I needed to make a symlink to my /etc/php5/conf.d/mcrypt.ini file in the following folders /etc/php5/apache2/conf.d/mcrypt.ini and /etc/php5/cli/conf.d/mcrypt.ini

Answer 22

Expanding on @JetLaggy:

After trying again and again to modify .bash_profile with the MAMP directory, I changed the file permissions for the MAMP php directory and was able to get 'which php' to show the proper directory. Trouble was that other functions didn't work, such as 'php -v'.

So I updated MAMP. http://documentation.mamp.info/en/mamp/installation/updating-mamp

This did the trick for my particular setup. I had to adjust my PATH to reflect the updated version of PHP, but once I did, everything worked!
