Your requirements could not be resolved to an installable set of packages. Problem 1 - spatie/laravel-data[3.9.0, ..., v3.x-dev] require illuminate/contracts ^9.30|^10.0 -> satisfiable by illuminate/contracts[v9.30.0, ..., 9.x-dev, v10.0.0, ..., 10.x-dev]. - Only one of these can be installed: illuminate/contracts[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, v11.0.0, ..., 11.x-dev], laravel/framework[v11.0.0, ..., 11.x-dev]. laravel/framework replaces illuminate/contracts and thus cannot coexist with it. - orchestra/testbench[v9.0.0, ..., 9.x-dev] require laravel/framework ^11.0 -> satisfiable by laravel/framework[v11.0.0, ..., 11.x-dev]. - Conclusion: don't install laravel/framework v11.0.3 (conflict analysis result) - Conclusion: don't install laravel/framework v11.0.4 (conflict analysis result) - Conclusion: don't install laravel/framework v11.0.5 (conflict analysis result) - orchestra/testbench-core[v9.0.1, ..., 9.x-dev] conflict with laravel/framework <11.0.3 || >=12.0.0. - orchestra/testbench[v9.0.0, ..., 9.x-dev] require orchestra/testbench-core ^9.0.1 -> satisfiable by orchestra/testbench-core[v9.0.1, 9.x-dev]. - Root composer.json requires orchestra/testbench ^9.0 -> satisfiable by orchestra/testbench[v9.0.0, 9.x-dev]. - Root composer.json requires spatie/laravel-data ^3.9 -> satisfiable by spatie/laravel-data[3.9.0, ..., v3.x-dev].
