Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires pestphp/pest-plugin-laravel ^2.3 -> satisfiable by pestphp/pest-plugin-laravel[v2.3.0, 2.x-dev]. - pestphp/pest-plugin-laravel[v2.3.0, ..., 2.x-dev] require laravel/framework ^10.44.0|^11.0 -> found laravel/framework[v10.44.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev] but it conflicts with your root composer.json require (9.*). Problem 2 - Conclusion: don't install illuminate/database v10.42.0 (conflict analysis result) - Conclusion: don't install illuminate/database v10.48.7 (conflict analysis result) - Conclusion: don't install illuminate/database v11.3.1 (conflict analysis result) - Only one of these can be installed: laravel/framework[v9.0.0-beta.1, ..., 9.x-dev], illuminate/database[v10.0.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev]. laravel/framework replaces illuminate/database and thus cannot coexist with it. - Root composer.json requires illuminate/database ^10.0|^11.0 -> satisfiable by illuminate/database[v10.0.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev]. - Root composer.json requires laravel/framework 9.* -> satisfiable by laravel/framework[v9.0.0-beta.1, ..., 9.x-dev].
