CakePHP 3.0 installation: intl extension missing from system

Juan Carlos picture Juan Carlos · Oct 9, 2014 · Viewed 101.2k times · Source

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

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.
