How to run Laravel 8 on MAMP?

Question

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

Fatal error: Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.1.0". You are running 8.0.8. in /Users/laravel-app/vendor/composer/platform_check.php on line 24

php --version

You need to realize that you have 2 versions of PHP installed on that Mac -- one is a web server, and one is a command line. Take your MAMP web server, and create a page that has nothing but <?php phpinfo(); in it. Then, visit that web page and it will give you a long list of information including the version of PHP. Usually you want to have the command line version and the web server version to be in sync, but that's your perogative.
