cannot execute php artisan command [php fatal error[

I have a laravel project I installed the composer and run

composer install

After that I executed the update command

composer update

on the project's root directory, and during the execution on the command

php artisan optimize

I got the error shown in the attached image.

When I try to execute any php artisan command I got the same error too.
