Did you do the following:
1: Change directory to your sites directory (cd ~/Sites/)
2: Create laravel project (composer create-project laravel/laravel projectname)
3: Change directory to the project you just created (cd projectname)
4: Set up your database details in the .env file (generally mySQL or sqlite)
5: Start your server (php artisan serve)
6: Install a frontend starter pack if you want UI eg Breeze (composer require laravel/breeze --dev)
7: Choose a scaffold (example blade) to install and run the install commands:
7.1 php artisan breeze:install
7.2 php artisan migrate
7.3 npm install
7.4 npm run dev
This is way to boot up a new project in laravel 9. However you can stop at step 4 and build your own views.
