How to install mcrypt on PHP 7.3.3 ubuntu

问题

I tried to follow: PHP Warning: PHP Startup: Unable to load dynamic library 'mcrypt.so'

sudo apt-get -y install gcc make autoconf libc-dev pkg-config
sudo apt-get -y install php7.2-dev
sudo apt-get -y install libmcrypt-dev
sudo pecl install mcrypt-1.0.1

I get:

pecl/mcrypt requires PHP (version >= 7.2.0, version <= 7.3.0, excluded versions: 7.3.0), installed version is 7.3.3-1+ubuntu14.04.1+deb.sury.org+1
No valid packages found
install failed

I use prestashop which require this

If anyone is using an AWS bitnami install w/ php7.3.10, the following is a layout with appropriate file paths (references listed below)

Check your PHP version

$ php -version

Install mcrypt extension

$ sudo apt-get -y install gcc make autoconf libc-dev pkg-config

$ sudo apt-get -y install libmcrypt-dev

If php version > 7.3.0

$ sudo pecl install mcrypt-1.0.2

Or the newest version: https://pecl.php.net/package/mcrypt

If php version <= 7.3.0

$ sudo pecl install mcrypt-1.0.1

When you are shown the prompt (Press [Enter] to autodetect)

> libmcrypt prefix? [autodetect] :

enable mcrypt in php.ini -> check if mcrypt is already in php.ini and maybe just needs to be uncommented

$ more /opt/bitnami/php/etc/php.ini | grep mcrypt

;extension=mcrypt.so

Add or uncomment extension=mcrypt.so in php.ini

$ emacs /opt/bitnami/php/etc/php.ini

You have to install version 1.0.2.

The error message clearly tells you 1.0.1 supports only PHP 7.2, not 7.3.

It's all documented on the official pecl/mcrypt page.

Release 1.0.2:

PHP Version: PHP version 7.4.0 or older

PHP Version: PHP 7.2.0 or newer

PEAR Package: PEAR 1.4.0 or newer

Release 1.0.1:

PHP Version: PHP version 7.3.0 or older

PHP Version: PHP 7.2.0 or newer

PEAR Package: PEAR 1.4.0 or newer

Use this, it's working perfectly in php-7.3:

sudo apt-get -y install gcc make autoconf libc-dev pkg-config
sudo apt-get -y install libmcrypt-dev
sudo pecl install mcrypt-1.0.1

Autodetect: HIT ENTER

sudo bash -c "echo extension=/usr/lib/php/[folder in your pc]/mcrypt.so > /etc/php/7.3/cli/conf.d/mcrypt.ini"

sudo bash -c "echo extension=/usr/lib/php/[folder in your pc]/mcrypt.so > /etc/php/7.3/apache2/conf.d/mcrypt.ini"

php -i | grep mcrypt
