I’ve used Composer install, when I give < Composer require League/flysystem > answer me:

    Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires php ^8,0.8 but your php version (8.0.8) does not satisfy that requirement.
  Problem 2
    - laravel/framework is locked to version v8.52.0 and an update of this package was not requested.
    - laravel/framework v8.52.0 requires league/flysystem ^1.1 -> found league/flysystem[1.1.0, ..., 1.x-dev] but it conflicts with your root composer.json require (^2.2).
  Problem 3
    - laravel/framework v8.52.0 requires league/flysystem ^1.1 -> found league/flysystem[1.1.0, ..., 1.x-dev] but it conflicts with your root composer.json require (^2.2).
    - laravel/sail v1.8.6 requires illuminate/console ^8.0|^9.0 -> satisfiable by laravel/framework[v8.52.0].
    - laravel/sail is locked to version v1.8.6 and an update of this package was not requested.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
