Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires php ^8.2 but your php version (8.1.31) does not satisfy that requirement. Problem 2 - Root composer.json requires sylius/twig-hooks ^0.6 -> satisfiable by sylius/twig-hooks[v0.6.0, v0.6.1]. - sylius/twig-hooks[v0.6.0, ..., v0.6.1] require symfony/config ^6.4 || ^7.0 -> found symfony/config[v6.4.0, ..., v6.4.14, v7.0.0, ..., v7.2.3] but these were not loaded, likely because it conflicts with another require. Problem 3 - Root composer.json requires sylius/twig-extra ^0.6 -> satisfiable by sylius/twig-extra[v0.6.0, v0.6.1]. - sylius/twig-extra[v0.6.0, ..., v0.6.1] require symfony/http-kernel ^6.4 || ^7.0 -> found symfony/http-kernel[v6.4.0, ..., v6.4.18, v7.0.0, ..., v7.2.3] but these were not loaded, likely because it conflicts with another require. Problem 4 - Root composer.json requires sylius/sylius ^1.13 -> satisfiable by sylius/sylius[v1.13.0, ..., v1.14.2]. - sylius/sylius[v1.13.0, ..., v1.14.2] require league/flysystem-bundle ^2.4 -> found league/flysystem-bundle[2.4.0] but it conflicts with your root composer.json require (^3.3).
