CakePHP 3.0 installation: intl extension missing from system

Question

Using the CakePHP docs, I am trying to install 3.0-beta2 using composer but I got this error:

cakephp/cakephp 3.0.x-dev requires ext-intl * -> the requested PHP extension intl is missing from your system

However, I know for sure that intl is installed (it shows on phpinfo). I'm using PHP 5.4.33/Apache 2.4.10.1

Answer 1

I faced the same problem today. You need to enable the intl PHP extension in your PHP configuration (.ini).

Solution Xampp (Windows)

1. Open /xampp/php/php.ini
2. Change ;extension=php_intl.dll to extension=php_intl.dll (remove the semicolon)
3. Copy all the /xampp/php/ic*.dll files to /xampp/apache/bin
4. Restart apache in the Xampp control panel

Solution Linux (thanks to Annamalai Somasundaram)

1. Install the php5-intl extension sudo apt-get install php5-intl

   1.1. Alternatively use sudo yum install php5-intl if you are on CentOS or Fedora.

2. Restart apache sudo service apache2 restart

Solution Mac/OSX (homebrew) (thanks to deizel)

1. Install the php5-intl extension brew install php56-intl
2. If you get No available formula for php56-intl follow these instructions.
3. Restart apache sudo apachectl restart

Eventually you can run composer install to check if it's working. It will give an error if it's not.

Answer 2

I faced the same issue in ubuntu 12.04

Installed: sudo apt-get install php5-intl

Restarted the Apache: sudo service apache2 restart

Answer 3

OS X Homebrew (May 2015):

The intl extension has been removed from the main php5x formulas, so you no longer compile with the --enable-intl flag.

If you can't find the new package:

$ brew install php56-intl
Error: No available formula for php56-intl

Follow these instructions: https://github.com/Homebrew/homebrew-php/issues/1701

$ brew install php56-intl
==> Installing php56-intl from homebrew/homebrew-php

When using MAMP

export PATH=/Applications/MAMP/bin/php/php5.6.2/bin:$PATH

Change php5.6.2 to the php version you use with MAMP

Hit ESC, Type :wq, hit Enter

source ~/.bash_profile

which php

2 Install Mac Ports

https://www.macports.org/install.php

sudo port install php5-intl OR sudo port install php53-intl

cp /opt/local/lib/php/extensions/no-debug-non-zts-20090626/intl.so /Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-20090626/

{take a good look at the folder names that u use the right ones}

3 Add extension

Now, add the extension to your php.ini file:

extension=intl.so

Answer 5

The error message clearly states what the problem is. You need the intl extension installed.

Step 1: install PHP intl you comfortable version

$sudo apt-get install php-intl

step 2:

For XAMPP Server intl extension is already installed, you need to enable this extension to uncomment below the line in your php.ini file. Php.ini file is located at c:\xampp\php\php.ini or where you have installed XAMPP.

Before uncomment:

;extension=php_intl.dll ;extension=php_mbstring.dll

After uncommenting:

extension=php_intl.dll extension=php_mbstring.dll

Answer 6

Short answer: activate intl extension in php_cli.ini. Thanks to @ndm for his input.
