Enable / install ext-intl on mac with mamp

[Filippo1996]

Hi, how can I enable / install on mac with mamp ext-intl?
When I try to run the composer install command, I get this series of errors

Problem 1
    - The requested PHP extension ext-intl * is missing from your system. Install or enable PHP's intl extension.
  Problem 2
    - Installation request for phpoffice/phpspreadsheet 1.13.0 -> satisfiable by phpoffice/phpspreadsheet[1.13.0].
    - phpoffice/phpspreadsheet 1.13.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
  Problem 3
    - Installation request for php-webdriver/webdriver 1.8.2 -> satisfiable by php-webdriver/webdriver[1.8.2].
    - php-webdriver/webdriver 1.8.2 requires ext-zip * -> the requested PHP extension zip is missing from your system.
  Problem 4
    - phpoffice/phpspreadsheet 1.13.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - maatwebsite/excel 3.1.19 requires phpoffice/phpspreadsheet ^1.10 -> satisfiable by phpoffice/phpspreadsheet[1.13.0].
    - Installation request for maatwebsite/excel 3.1.19 -> satisfiable by maatwebsite/excel[3.1.19].

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

how can i solve? thanks
