من یک پروژه ای که در گیت لب بهم دادن رو میخوام php artisan serve کنم اما ارور میده

 require(/home/netwons/proj/vhotel-master/vhotel/vendor/autoload.php): failed to open stream: No such file or directory in /home/netwons/proj/vhotel-master/vhotel/artisan on line 18

composer update هم میزنم باز مشکل وجود دارد

 Problem 1
    - Installation request for simplesoftwareio/simple-qrcode ^4.1 -> satisfiable by simplesoftwareio/simple-qrcode[4.1.0].
    - simplesoftwareio/simple-qrcode 4.1.0 requires ext-gd * -> the requested PHP extension gd is missing from your system.
  To enable extensions, verify that they are enabled in your .ini files:
