How to run Laravel 8 on MAMP?

I have this in my composer.json

"require": {
    "php": "^8",
    "alkhachatryan/laravel-web-console": "^3.3",
    "barryvdh/laravel-dompdf": "^0.9.0",
    "doctrine/dbal": "^2.10",
    "fideloper/proxy": "^4.2",
    "fruitcake/laravel-cors": "^1.0",
    "guzzlehttp/guzzle": "^6.3",
    "intervention/image": "^2.3",
    "laravel/framework": "^8",
    "laravel/tinker": "^2.0",
    "laravelcollective/html": "~6.0",
    "league/flysystem-aws-s3-v3": "~1.0",
    "pusher/pusher-php-server": "^4.1"
},

I'm trying to run my Laravel app via MAMP v6.6

I kept getting
