i have problem to run laravel 5 project on local

i cloned a Laravel 5 project and try to run it . i got some errors in composer install composer update php artisan migrate

(actually all of "php aritsan" commands)

i got this error :

In Connector.php line 70:

  SQLSTATE[HY000] [2006] MySQL server has gone away  


In Connector.php line 70:

  PDO::__construct(): Error while reading greeting packet. PID=21464

i tried " php artisan clear " but i got same error .

i am trying to run this project on local . i use php 7.4 i use wamp.
