Locale class not found on CakePHP 3

Question

I just downloaded the files from this link , extracted and tried to execute, but I had this error:

Fatal error: Class 'Locale' not found in D:\xampp\htdocs\cake-3-beta-2\vendor\cakephp\cakephp\src\I18n\I18n.php on line 229 

I work on localhost with xampp ... I had the same problem with beta versions 1 and 2.

Answer 1

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

Xampp Solution (Windows)

• Open /xampp/php/php.ini
• Change ;extension=php_intl.dll to extension=php_intl.dll (remove the semicolon)
• Copy all the /xamp/php/ic*.dll files to /xampp/apache/bin
• Restart apache in Xampp Control Panel

Linux solution (thanks to Annamalai Somasundaram)

• Install extension php5-intl sudo apt-get install php5-intl

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

• Restart apache sudo service apache2 restart

Mac / OSX solution (homebrew) (thanks deizel)

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

In the end, you can run composer install to see if it works.
