This package does not require any PHP extentions.
See

ci3-to-4-upgrade-helper/composer.json

Lines 23 to 27 in e8cde5c

	"require": {
	"php": "^7.4 || ^8.0",
	"kenjis/ci3-like-captcha": "^1.0.1",
	"kenjis/phpunit-helper": "^1.1.2"
	},

If you cannot install this via composer, it seems you don't have PHP extensions that CI4 requires.
If so, you cannot run CI4 on your server.
