Illuminate packages conflict with other required

[Echecivuole]

Hello,
while installing the package I receive these errors while trying to install desktop notifier:

Problem 1 - nunomaduro/laravel-desktop-notifier v2.5.0 requires illuminate/support ^6.0|^7.0|^8.0 -> found illuminate/support[v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev] but it conflicts with another require. - nunomaduro/laravel-desktop-notifier v2.5.1 requires illuminate/support ^6.20|^7.29|^8.12 -> found illuminate/support[v6.20.0, v6.20.1, v6.20.2, 6.x-dev, v7.29.0, v7.29.1, v7.29.2, 7.x-dev, v8.12.0, ..., 8.x-dev] but it conflicts with another require. - Root composer.json requires nunomaduro/laravel-desktop-notifier ^2.5 -> satisfiable by nunomaduro/laravel-desktop-notifier[v2.5.0, v2.5.1].

When I try to install the above Illuminate support I still get similar error:

Problem 1 - Root composer.json requires illuminate/support ^8.12, found illuminate/support[v8.12.0, ..., 8.x-dev] but it conflicts with another require.

Can you help?

What version of Laravel are you using? Could you perhaps post the contents of the require/require-dev section in your Composer JSON?

I use Laravel 5.7 with these:
"require-dev": { "filp/whoops": "^2.0", "fzaninotto/faker": "^1.4", "mockery/mockery": "^1.0", "nunomaduro/collision": "^2.0", "phpunit/phpunit": "^7.0", "symfony/var-dumper": "4.4.x-dev" },

This package dropped support for Laravel 5.7 in v2.4.0, so you'll need to use an older version of the package. Can you try using composer require nunomaduro/laravel-desktop-notifier ^2.3.0?

[Echecivuole]

which laravel version is valid for the 2.4.0?

Laravel 6 and above.
