Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires PHP extension ext-yaml * but it is missing from your system. Install or enable PHP's yaml extension.
To enable extensions, verify that they are enabled in your .ini files:
- /opt/homebrew/etc/php/8.0/php.ini
- /opt/homebrew/etc/php/8.0/conf.d/20-pcov.ini
- /opt/homebrew/etc/php/8.0/conf.d/ext-opcache.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-yaml` to temporarily ignore these required extensions.
