I newly install Dompdf in Laravel Project via Composer (composer require barryvdh/laravel-dompdf). After enter the Command Terminal Reply Following Errors.
Problem 1
- dompdf/dompdf v0.7.0 requires ext-gd * -> the requested PHP extension gd is missing from your system.
- barryvdh/laravel-dompdf v0.7.0 requires dompdf/dompdf ^0.7 -> satisfiable by dompdf/dompdf[v0.7.0].
- Installation request for barryvdh/laravel-dompdf ^0.7.0 -> satisfiable by barryvdh/laravel-dompdf[v0.7.0].

How to Solve this Error
I already Installed GD using Following comment. sudo apt-get install php5-gd and also Apache Server Restarted. My Laravel Version is 5.3 and Ubuntu Version is 14.04
回答1:
I have installed php7, I did the following to solve exactly the same error
sudo apt-get install php7.0-gd
sudo apt-get install php7.0-intl
sudo apt-get install php7.0-xsl
回答2:
If you are working in PHP version 5.* then you have to install
sudo apt-get install php5-gd
And if you are working in PHP version 7.* then you have to install
sudo apt-get install php7.0-gd
Hope it will work...
And if you are working in PHP version 7.2 then you have to install
sudo apt-get install php7.2-gd... it worked for me
回答3:
It may not be enabled for php-cli, you can enable like this;
sudo phpenmod gd
UPDATE
I guess, you are using ppa:ondrej php package (5.6), which is confusing you with default ubuntu 14.04 php package (5.5.9).
To install php 5.6 gd library from ppa:ondrej, you should use:
sudo apt-get install php5.6-gd
回答4:
Open your php.ini and uncomment this line:
;extension=php_gd2.dll
回答5:
if you are working in PHP version 7.2 then you have to install
sudo apt-get install php7.2-gd

For Php 7.4.2
- sudo apt-get install php7.4-gd
- sudo phpenmod gd
回答7:
Before installing the missing dependency, you need to check which version of PHP is installed on your system.
php -v
PHP 7.2.10-0ubuntu0.18.04.1 (cli) (built: Sep 13 2018 13:45:02) ( NTS )

In this case it's php7.2. apt search php7.2 returns all the available PHP extensions.
apt search php7.2

You can now proceed to installing the missing dependency by running:
sudo apt install php7.2-gd
回答8:
For php 7.1
sudo apt-get install php7.1-gd
Cheers!
回答9:
The solution is quite simple.
In your php.ini, just uncomment the line extension=php_gd2.dll (or .so extension for unix systems.)
Hope it helps.
回答10:
Using Manjaro(Arch) Linux:
$ sudo pacman -S php-gd
In file /etc/php/php-ini, add the line:
extension=gd.so
回答11:
For Windows : Uncomment this line in your php.ini file
;extension=php_gd2.dll
If the above step doesn't work uncomment the following line as well:
;extension=gd2
回答12:
This worked for me:
composer require "ext-gd:*" --ignore-platform-reqs
回答13:
On CentOS 7, try running following command:
sudo yum install php72u-gd.x86_64
