Я пытаюсь установить laravel/ui
для Laravel 6.4, но когда я пытаюсь установить через composer, я получаю сообщение об ошибке Your requirements could not be resolved to an installable set of packages.
Problem 1
- The requested package laravel/framework (locked at v6.4.0, required as ^5.0) is satisfiable by laravel/framework[v6.4.0], but these conflict with your requirements or minimum-stability.
Problem 2
- laravel/framework v5.0.9 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.

To enable extensions, verify that they are enabled in your .ini files:

Installation failed, reverting ./composer.json to its original content.
Я также пытался установить его вручную, но безрезультатно. composer.json: composer.json
