tymon/jwt-auth for authentication not working in laravel V8

Are you certain that the installation went though without any issues?

What is the output of (any errors?)

composer require tymon/jwt-auth  "^1.0"

Yes bro.. i have installed "^1.0" installed successfully but after publish the provider and generate secret key not working...

config/app.php
$provider = [
	Tymon\JWTAuth\Providers\LaravelServiceProvider::class,
 ]

php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"

php artisan jwt:secret

Try not adding it manually in the app.php file

I just ran those commands without any issues in laravel 8, but I didnt add it to the app.php

Then php artisan jwt:secret not working giving error

 There are no commands defined in the "jwt" namespace.

This command running successfully but not creating jwt.php file in config folder

Sounds alot like it hasnt installed properly.

Can you post you composer.json ?

Strange. Try the following

composer update
php artisan optimize:clear
php artisan jwt:secret

Thanks, @sinnbeck bro...
