如何在 Ubuntu 上为 PHP7 安装 GMP

Question

I was getting the following error when trying to run composer update on a SimpleSAML project.

- openid/php-openid dev-master requires ext-gmp * -> the requested PHP extension gmp is missing from your system.

Running sudo apt-get install php5-gmp did not work and neither did sudo apt-get install php7-gmp

Answer 1

To install GMP for PHP7.0 on Ubuntu, run: sudo apt-get install php7.0-gmp

Make sure your php.ini contains the following: extension=php_gmp.so

To find out where your php.ini is located, run: php --ini

Answer 2

对于 PHP 7.2：

sudo apt-get install php7.2-gmp

Answer 3

PHP 7 中安装扩展的新方法是只写“php-EXTENSION”在这种情况下它很简单：

sudo apt-get install php-gmp

Answer 4

For PHP 7.4:

sudo apt-get install php7.4-gmp

SO: Ubuntu 20.04

Answer 5

Thank you it helps me. I use PHP 7.2. Therefore, I run:

1. sudo apt-get install php7.2-gmp
2. extension=php_gmp.so

Answer 6

apt-get install php7.1-gmp

就是这样。

Answer 7

If you are running php 7.2 and above, then

sudo apt-get install php7.2-gmp

or you can as well install bcmath extension using

sudo apt-get install php7.2-bcmath

I recommend you install both of them, after complete install restart apache

sudo service apache2 reload

sudo service apache2 restart

Answer 8

For docker based on official php images like php:7.2-fpm

Just add this to Dockerfile

RUN apt install -y libgmp-dev && docker-php-ext-install gmp

Answer 9

for centos

sudo yum install php-gmp

for ubuntu

sudo apt install php-gmp

also enable php extension in ini file

extension=php_gmp.so

Answer 10

UPDATE: apt-get has evolved over the years into just apt. On modern systems this will detect the php version, etc.

sudo apt install php-gmp

Answer 11

It's better to search using package or dependency manager installed in machine. For yum , you can search using yum search gmp and then install.

yum search gmp

This will yield these search results

Loaded pluginss: extras_suggestions, langpacks, priorities, update-motd
170 packages excluded due to repository priority protections
========================================================= N/S matched: gmp ==========================================================
perl-Math-BigInt-GMP.x86_64 : Math::BigInt::GMP Perl module
python-gmpy2.x86_64 : Python 2 interface to GMP, MPFR, and MPC
gmp.x86_64 : A GNU arbitrary precision library
gmp.i686 : A GNU arbitrary precision library
gmp-devel.x86_64 : Development tools for the GNU MP arbitrary precision library
gmp-static.x86_64 : Development tools for the GNU MP arbitrary precision library
mingw32-gmp.noarch : Cross-compiled GNU arbitrary precision library

perl-Math-GMP.x86_64 : High speed arbitrary size integer math
php-gmp.x86_64 : A module for PHP applications for using the GNU MP library

Now install extension with: yum install php-gmp.x86_64

Answer 12

For PHP 7.3 try this.

sudo apt-get install php7.3 -gmp
extension=php_gmp.so

in Ubuntu
