Error installing consoletvs/charts:5.*?

Question

Laravel

I'm trying to install composer require consoletvs/charts:5.*

In Date.php line 386:

  Declaration of Jenssegers\Date\Date::add($interval) must be compatible with Carbon\Carbon::add($unit, $value = 1, $overflow = NULL)

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 255

In general, how to win ?, it is the 5th version that is needed, the 6th is heavily redesigned, it is not clear how to work with it, there are few examples, and those that exist have not been launched.
