Composer detected issues in your platform

Hello everyone,

I am using docker in my PHP development and PHP version is 7.4, I copied one of my projects I developed on WAMP server which runs PHP 8.0.2 to the docker environment and when I try to run it, it gives me this error:

Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.0.2". You are running 7.4.1

"require": {
        "php": "^7.4|^8.0",
        "aacotroneo/laravel-saml2": "^2.1",
        "fruitcake/laravel-cors": "^2.0",
        "guzzlehttp/guzzle": "^7.0.1",
        "inertiajs/inertia-laravel": "^0.5.2",
        "laravel/framework": "^8.75",
        "laravel/sanctum": "^2.11",
        "laravel/tinker": "^2.5"
    }

none of the above dependencies won't work on PHP 7.4 so what is the issue?
