Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires api-platform/state @dev -> satisfiable by api-platform/state[dev-main, 4.0.x-dev (alias of dev-main)]. - laravel/framework[v11.0.0, ..., 11.x-dev] require symfony/http-kernel ^7.0 -> satisfiable by symfony/http-kernel[v7.1.0-BETA1, ..., 7.2.x-dev]. - You can only install one version of a package, so only one of these can be installed: symfony/http-kernel[v6.4.0-BETA1, ..., 6.4.x-dev, v7.1.0-BETA1, ..., 7.2.x-dev]. - api-platform/state[dev-main, 4.0.x-dev] require symfony/http-kernel ^6.4 || 7.0 -> satisfiable by symfony/http-kernel[v6.4.0-BETA1, ..., 6.4.x-dev]. - Conclusion: install api-platform/state dev-main (conflict analysis result) - Root composer.json requires laravel/framework ^11.0 -> satisfiable by laravel/framework[v11.0.0, ..., 11.x-dev].
