Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires larastan/larastan ^3 -> satisfiable by larastan/larastan[v3.0.0, ..., v3.8.0]. - Root composer.json requires laravel/framework ^10 -> satisfiable by laravel/framework[v10.48.29, v10.49.0, v10.49.1]. - larastan/larastan[v3.0.0, ..., v3.0.4] require illuminate/support ^11.15.0 -> satisfiable by illuminate/support[v11.15.0, ..., v11.46.1]. - larastan/larastan v3.1.0 requires illuminate/support ^11.15.0 || ^12.0 -> satisfiable by illuminate/support[v11.15.0, ..., v11.46.1, v12.0.0, ..., v12.38.1]. - larastan/larastan v3.2.0 requires illuminate/support ^11.41.3 || ^12.0 -> satisfiable by illuminate/support[v11.41.3, ..., v11.46.1, v12.0.0, ..., v12.38.1]. - larastan/larastan v3.3.0 requires illuminate/support ^11.42.2 || ^12.0 -> satisfiable by illuminate/support[v11.43.0, ..., v11.46.1, v12.0.0, ..., v12.38.1]. - larastan/larastan[v3.3.1, ..., v3.8.0] require illuminate/support ^11.44.2 || ^12.4.1 -> satisfiable by illuminate/support[v11.44.2, ..., v11.46.1, v12.4.1, ..., v12.38.1]. - Conclusion: don't install laravel/framework v10.49.0 (conflict analysis result) - Conclusion: don't install laravel/framework v10.49.1 (conflict analysis result) - Only one of these can be installed: illuminate/support[v6.0.0, ..., v6.20.44, v7.0.0, ..., v7.30.6, v8.0.0, ..., v8.83.27, v9.0.0, ..., v9.52.16, v10.0.0, ..., v10.49.0, v11.0.0, ..., v11.46.1, v12.8.0, ..., v12.38.1], laravel/framework[v10.48.29, v10.49.0, v10.49.1]. laravel/framework replaces illuminate/support and thus cannot coexist with it.
