CodeIgniter 4 problem installing with composer

Hello,
I'm having problems trying to install CodeIgniter 4 via Composer, on a local server (xampp). Any idea what the error may be or how I can fix it?
The code that throws me is the following:
 

Code:

  PS C:\Users\PuercoRico> cd D:\xampp\htdocs
PS D:\xampp\htdocs> composer create-project codeigniter4/appstarter ci4 -s rc
Installing codeigniter4/appstarter (4.0.0-rc.4)
  - Installing codeigniter4/appstarter (4.0.0-rc.4): Loading from cache
Created project in ci4
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - codeigniter4/framework v4.0.0-rc.3 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - codeigniter4/framework v4.0.0-rc.2.1 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - codeigniter4/framework v4.0.0-rc.2 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - codeigniter4/framework v4.0.0-rc.1 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - codeigniter4/framework 4.0.0-rc.4 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - Installation request for codeigniter4/framework ^4@rc -> satisfiable by codeigniter4/framework[4.0.0-rc.4, v4.0.0-rc.1, v4.0.0-rc.2, v4.0.0-rc.2.1, v4.0.0-rc.3].

  To enable extensions, verify that they are enabled in your .ini files:
    - D:\xampp\php\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
