Answer 1

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

Answer 2

Isn't it obvious? To use the version of laravel/passport ^ 8.0 .

You must install laravel 6. Required statement: https://laravel.com/docs/6.x/upgrade

What is the command you are using?

composer require laravel/passport

I recommend you use it. Laravel version you use will make the appropriate installation.

Answer 3

use composer require laravel/passport=^7.4

Answer 4

Can you try to include a previous version of passport, eg composer require laravel/passport "7.5.1"

I would recommend Özgür Can Karagöz answer though if you have the time and your project isn't huge.

Answer 5

composer require laravel/passport "7.5.1"

is working for laravel version 5.8*
