for laravel 9 and php 8.1 i had error at install

[mohammad-salehealizadegan]

Problem 1
- rinvex/laravel-categories[v6.1.0, ..., v6.1.2] require rinvex/laravel-support ^6.0.0 -> satisfiable by rinvex/laravel-support[v6.0.0, ..., v6.1.3].
- rinvex/laravel-support[v6.0.0, ..., v6.0.3] require felixkiss/uniquewith-validator ^3.4.2 -> satisfiable by felixkiss/uniquewith-validator[3.4.2].
- felixkiss/uniquewith-validator 3.4.2 requires illuminate/support ^5.5|^6.0|^7.0|^8.0 -> found illuminate/support[v5.5.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.
- rinvex/laravel-support[v6.1.0, ..., v6.1.3] require felixkiss/uniquewith-validator dev-l9-compatibility -> found felixkiss/uniquewith-validator[dev-master, 1.0.0, ..., 1.1.4, 2.0.0, ..., 2.0.8, 3.0.0, ..., 3.4.2] but it does not match the constraint.
- Root composer.json requires rinvex/laravel-categories ^6.1 -> satisfiable by rinvex/laravel-categories[v6.1.0, v6.1.1, v6.1.2].

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

@mohammad-salehealizadegan great, glad you found your way.

For reference if anyone else having the same issue, please check these instructions
https://github.com/rinvex/laravel-support#note-for-laravel-v9

Note when using this package with Laravel v9

This package requires felixkiss/uniquewith-validator dependency, which is not yet compatible with Laravel v9! However as a temporary workaround, add Laravel Shift's fork to the repositories property of your project root composer.json:

{
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/laravel-shift/uniquewith-validator.git"
        }
    ]
}

Update: we dropped the felixkiss/uniquewith-validator dependency 🙂 rinvex/laravel-support@2bf69b8
