problem installing jwt_auth

I am trying to create API for USER authentication, I tried Fortify but is not easy if you don't want to use views (or even possible?).

I found this library but seems that doesn't work with laravel 8.

I created a new laravel project and the first thing I did is trying to install it.

this is what i get

PS C:\LaravelProject\jwt_auth_test> composer require tymon/jwt-auth
Using version ^0.5.12 for tymon/jwt-auth
./composer.json has been updated
Running composer update tymon/jwt-auth
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 tymon/jwt-auth ^0.5.12 -> satisfiable by tymon/jwt-auth[0.5.12].
    - tymon/jwt-auth 0.5.12 requires illuminate/support ~5.0 -> found illuminate/support[v5.0.0, ..., 5.8.x-dev] but these were not loaded, likely because it conflicts with another require.


Installation failed, reverting ./composer.json and ./composer.lock to their original content.
