Your requirements could not be resolved to an installable set of packages. Problem 1 - laravel/framework[v7.0.0, ..., v7.28.4] require php ^7.2.5 -> your php version (8.0.30) does not satisfy that requirement. - illuminate/support[v10.33.0, ..., 10.x-dev] require php ^8.1 -> your php version (8.0.30) does not satisfy that requirement. - Only one of these can be installed: laravel/framework[v7.0.0, ..., 7.x-dev], illuminate/support[v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev, v10.0.0, ..., 10.x-dev]. laravel/framework replaces illuminate/support and thus cannot coexist with it. - larastan/larastan[v2.7.0, ..., 2.x-dev] require illuminate/support ^9.52.16 || ^10.28.0 -> satisfiable by illuminate/support[v9.52.16, 9.x-dev, v10.28.0, ..., 10.x-dev]. - Root composer.json requires larastan/larastan ^2.7.0 -> satisfiable by larastan/larastan[v2.7.0, 2.x-dev]. - Root composer.json requires laravel/framework 7.* -> satisfiable by laravel/framework[v7.0.0, ..., 7.x-dev].
