Como instalar o projeto pelo VSCode?

Estou tentando instalar o projeto que foi fornecido no Zip, mas, ao dar o composer install ele retorna erro;

Generating optimized autoload files
Deprecation Notice: Class Egulias\EmailValidator\Exception\ExpectedQPair located in D:/xampp/htdocs/curso-e2e/vendor/egulias/email-validator/EmailValidator\Exception\ExpectingQPair.php does not comply with psr-4 autoloading standard. It will not autoload anymore in Composer v2.0. in phar://C:/ProgramData/ComposerSetup/bin/composer.phar/src/Composer/Autoload/ClassMapGenerator.php:201

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

E os outros comandos o VSCode da um alerta
