- pestphp/pest-plugin-laravel v1.1.0 requires laravel/framework ^7.0 || ^8.0 -> found laravel/framework[v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev] but it conflicts with your root composer.json require (10.*).
- pestphp/pest-plugin-laravel v1.2.0 requires laravel/framework ^7.0 || ^8.0 || ^9.0 -> found laravel/framework[v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev] but it conflicts with your root composer.json require (10.*).
- pestphp/pest-plugin-laravel v1.3.0 requires laravel/framework ^7.30.6 || ^8.83.23 || ^9.30.1 -> found laravel/framework[v7.30.6, 7.x-dev, v8.83.23, ..., 8.x-dev, v9.30.1, ..., 9.x-dev] but it conflicts with your root composer.json require (10.*).
- Root composer.json requires pestphp/pest-plugin-laravel ^1.1 -> satisfiable by pestphp/pest-plugin-laravel[v1.1.0, ..., 1.x-dev].
- Conclusion: don't install illuminate/contracts v9.28.0 (conflict analysis result)
- Conclusion: don't install illuminate/contracts v9.0.0 (conflict analysis result)
- Conclusion: don't install illuminate/contracts v9.47.0 (conflict analysis result)
- pestphp/pest-plugin-laravel[v1.4.0, ..., 1.x-dev] require laravel/framework ^7.30.6 || ^8.83.27 || ^9.47.0 || ^10.0.0 -> satisfiable by laravel/framework[v10.0.0, ..., 10.x-dev].
- Only one of these can be installed: laravel/framework[v10.0.0, ..., 10.x-dev], illuminate/contracts[v9.0.0-beta.1, ..., 9.x-dev]. laravel/framework replaces illuminate/contracts and thus cannot coexist with it.
- Root composer.json requires illuminate/contracts ^9.0 -> satisfiable by illuminate/contracts[v9.0.0-beta.1, ..., 9.x-dev].
