Answer

If you didn’t download laravel the traditional way by running composer create-project --prefer-dist laravel/laravel my-app-name or laravel new my-app-name(if you have the laravel/installer installed globally on your system. Then you need to run composer install or composer update.

If this solves your problem then you might run into another problem, at this point, you should generate an APP_KEY by running php artisan key:generate
