To install the most recent version laravel/passport for Laravel Framework 5.8, run the following command

composer require laravel/passport

If you are still getting an error then install laravel/passport v7.5.1

Add to composer.json file:

"require": {
        "laravel/passport": "^7.5.1"
    },

After, Run this command in the command prompt: composer update

I tested laravel/passport v7.5.1 It is compatible with Laravel Framework 5.8

NOTE: If you need this version of "laravel/passport": "^8.0" then you must need laravel 6
