Can't install on Laravel 8 and Carbon 2

[brunoabcn]

Hi, I'm trying to install it on my project and send me the next list of errors.

Problem 1

- Root composer.json requires laravel/framework ^8.69 -> satisfiable by laravel/framework[v8.69.0, ..., v8.83.23].

You can also try re-running composer require with an explicit version constraint, e.g. "composer require typehints/laravel-unused:*" to figure out if any version is installable, or "composer require typehints/laravel-unused:^2.1" if you know which you need.

Installation failed, reverting ./composer.json to its original content.

I have installed on my project

Laravel 8.69
Carbon 2.0

Any Ideas?
