No package found

[adantart]

How can I install this package ?
There's no package from composer.

I've tried installing this one

composer require rollbar/rollbar-laravel

as shown in https://docs.rollbar.com/docs/laravel

but it's not working. It does not register any service.

It installs the v.1.3.2

Then I tried to force it:

composer require rollbar/rollbar-laravel:v8.0.0

but I got this:

./composer.json has been updated
Running composer update rollbar/rollbar-laravel
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires rollbar/rollbar-laravel v8.0.0 -> satisfiable by rollbar/rollbar-laravel[v8.0.0].
    - rollbar/rollbar-laravel v8.0.0 requires illuminate/support ^10.0 -> found illuminate/support[v10.0.0, ..., 10.x-dev] but these were not loaded, likely because it conflicts with another require.

Any idea ? :-(
