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

in ubuntu 14.04 based on your php version : 5.6,7.0,7.1,7.2,7.3

sudo apt-get install php{version}-mcrypt

sudo apt-get install php7.1-mcrypt

sudo phpenmod mcrypt 

Answer 2

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 3

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 4

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 5

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 !

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
