php artisan serve not working in VS Code on Linux

Hi,

I installed PHP 8, phpMyAdmin, apache2, Composer and Laravel on my Linux laptop. When I type: "php artisan serve" in VS Code, I get: "Could not open input file: artisan".

I copied the Laravel project I was working on from my Linux desktop to my Linux laptop via a USB drive. The Laravel project folder is inside the Linux Home folder.

This is from the Linux terminal:

To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php8/cli/php.ini
    - /etc/php8/conf.d/20-mysqlnd.ini
    - /etc/php8/conf.d/bz2.ini

You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-fileinfo` to temporarily ignore these requ
ired extensions.
