Composer install

Я скачал проект с github. Проект на laravel. Первая команда это composer install. После у меня вылетает следующее:

**Deprecation warning: require.extended-bread-form-fields is invalid, it should have a vendor name, a forward slash, and a package name. The vendor and package name can be words separated by -, . or _. The complete name should match "^[a-z0-9]([_.-]?[a-z0-9]+)*/[a-z0-9](([_.]?|-{0,2})[a-z0-9]+)*$". Make sure you fix this as Composer 2.0 will error.

  To enable extensions, verify that they are enabled in your .ini files:
    - C:\MAMP\bin\php\php7.4.1\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.**

Я проигнорировал эти предупреждения и ввожу php artisan key:generate и снова вот это:

PHP Fatal error:  require(): Failed opening required 'C:\MAMP\htdocs\KioskInfo-master/vendor/autoload.php' (include_path='.;C:\php\pear') in C:\MAMP\htdocs\KioskInfo-master\artisan on line 18**. 

Открываю этот файл и не знаю, что дальше.
