To enable extensions, verify that they are enabled in those .ini files - Vagrant/Ubuntu/Magento 2.0.2

问题

When installing Magento 2.0.2 via composer getting this error:

Problem 1
 - Installation request for magento/product-enterprise-edition 2.0.2 -> satisfiable by magento/product-enterprise-edition[2.0.2].
 - magento/product-enterprise-edition 2.0.2 requires ext-gd * -> the requested PHP extension gd is missing from your system.

To enable extensions, verify that they are enabled in those .ini files:

- /etc/php5/cli/php.ini
- /etc/php5/cli/conf.d/05-opcache.ini
- /etc/php5/cli/conf.d/10-pdo.ini
- /etc/php5/cli/conf.d/20-curl.ini
- /etc/php5/cli/conf.d/20-imap.ini
- /etc/php5/cli/conf.d/20-json.ini
- /etc/php5/cli/conf.d/20-mcrypt.ini
- /etc/php5/cli/conf.d/20-pdo_pgsql.ini
- /etc/php5/cli/conf.d/20-pgsql.ini
- /etc/php5/cli/conf.d/20-pspell.ini
- /etc/php5/cli/conf.d/20-readline.ini

You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

I have installed php5-cli, php5-curl.

First installed sudo apt-get install php5-gd, then sudo apt-get install php5-intl and last one was sudo apt-get install php5-xsl. After that, it's installing as it should.

@Verse answer works fine. But there is a small thing I would like to add. instead of installing php5-mbstring, php5-gd, php5-intl, php5-xsl. This answer is based on @Regolith answer: Package has no installation candidate .

Install according to your php-version.

First check which php version you have by sudo php -v. I have php7 so the result is:

PHP 7.0.28-0ubuntu0.16.04.1 (cli) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
   with Zend OPcache v7.0.28-0ubuntu0.16.04.1, Copyright (c) 1999-2017, by Zend Technologies

since i have php7, I will do the following to list the php packages:
sudo apt-cache search php7-*

this returned

libapache2-mod-php7.0 - server-side, HTML-embedded scripting language (Apache 2 module)
php-all-dev - package depending on all supported PHP development packages

now to install packages run the following command with your desired package

sudo apt-get install -y php7.0-gd, php7.0-intl, php7.0-xsl, php7.0-mbstring

Note: php7.0-mbstring, php7.0-gd php7.0-intl php7.0-xsl are the package that are listed above.

UPDATE: Don't forget to restart apache/<your_server>

sudo service apache2 reload

回答7:

First installed

sudo apt-get install php5-gd

then

sudo apt-get install php5-intl

and last one was

sudo apt-get install php5-xsl

After that, it is installing as it should.

回答8:

The exact name of the extension depends on the repository from which you got PHP but look here. For example on CentOS:

yum install -y php56w php56w-opcache php56w-xml php56w-mcrypt php56w-gd php56w-devel php56w-mysql php56w-intl php56w-mbstring php56w-bcmath

回答9:

On Ubuntu 16.04 php7 is now the default, so if you follow the top answers and are still having this issue, check your php version.

php --version

If your default php version is php7, but you followed an answer using php5 packages, you can use the following command to set the default version of php to php5.6:

sudo update-alternatives --set php $(which php5.6)

回答10:

I used below to fix issue

yum install -y php-intl php-xsl php-opcache php-xml php-mcrypt php-gd php-devel php-mysql php-mbstring php-bcmath

回答11:

ubuntu users try this

apt-get install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-gd php7.2-mysql php7.2-curl php7.2-intl php7.2-xsl php7.2-mbstring php7.2-zip php7.2-bcmath php7.2-soap php-xdebug php-imagick

this is work for php 7.2 but you can change this 7.2 to 5.2 and run this command it is work.

回答12:

For me

sudo apt-get install php5-mcrypt 

solved the issue

回答13:

Gonna post this answer here after seeing some of the answers (including the accepted one) which claim to "do the trick". First, we need to identify the issue before fixing it.

the requested PHP extension gd is missing from your system.

As the above line clearly states, we need to install the extension php-gd.

So, we can go with sudo apt install php<version>-gd and it should fix this error unless the system needs more extensions which happens to be the exact case here in the system in question. It needs a couple more extensions php-intl and php-xsl. So let it be mbstring or mcrypt, you should install whatever the extensions your system is missing. How can you find what is missing? Just read the error message, it is there.

回答14:

It helped my case to install the right curl version

sudo apt-get install php5-curl

回答15:

1. Open the xampp/php/php.ini file in any editor
2. Search ";extension=php_intl.dll"

3. Remove the starting semicolon ( ; )

   Like: ;extension=php_intl.dll to extension=php_intl.dll

This helped me.
