title: I'am getting an error --- In ProviderRepository.php line 208: Class 'Tymon\JWTAuth\Providers\LaravelServiceProvider' not found
body: <p>I'am new to laravel, and this is my first question because I could not find a solution anywhere. 
  I implemented JWT-token somehow and it worked until I mess it up. Now when I type php artisan serve I get that error, or when I try to publish. I tried everything like in question --- <a href="https://stackoverflow.com/questions/50986513/laravel-5-6-26-error-class-tymon-jwtauth-providers-laravelserviceprovider-not">Laravel 5.6.26 Error- Class &#39;Tymon\JWTAuth\Providers\LaravelServiceProvider&#39; not found</a> --- but it won't work.
  When I add in composer.json "tymon/jwt-auth": "^0.5.12"  I get an error class LaravelServiceProvider not found, and when I change it to "tymon/jwt-auth": "^1.0.0-beta.3" or "tymon/jwt-auth": "^1.0.0-rc.2" then I ger error JWTAuthServiceProvider not found. I also tried composer require illuminate/auth but it won't work. Can I get some help please.</p>
