title: Laravel Lumen Memcached not found
body: <p>Ok, I just started with Lumen and I'm trying to use the Auth, but a call to either Auth::check or any other function of Auth.. leads to the below Error
  <strong>Fatal error: Class 'Memcached' not found in   vendor\illuminate\cache\MemcachedConnector.php on line 52</strong>.
  I don't want to use Memcached never used it before.</p>
  
  <p>I disabled it in the <strong>.env</strong> file and set the <strong>CACHE_DRIVER</strong> and <strong>SESSION_DRIVER</strong> to array, but still shows the same error. </p>
  
  <p>I decided not to use Auth again and to manually handle my authetication with sessions/tokens, but enabling the MiddleWare StartSession results to the same error.</p>
  
  <pre><code>$app-&gt;middleware([
   // 'Illuminate\Cookie\Middleware\EncryptCookies',
   // 'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
    'Illuminate\Session\Middleware\StartSession',
   // 'Illuminate\View\Middleware\ShareErrorsFromSession',
   // 'Laravel\Lumen\Http\Middleware\VerifyCsrfToken',
  ]);
  </code></pre>
  
  <p>Please I'd be so glad if anyone can really help me out here</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>After going A little Deep in the framework
  I Hard Coded the session driver name in the <code>SessionManager</code> Class
  within the method <code>getSessionConfig</code></p>
  
  <pre><code>public function getSessionConfig()
  {
      $this-&gt;setDefaultDriver("cookie");//I added this line
      return $this-&gt;app['config']['session'];
  }
  </code></pre>
  
  <p>It works though but not a good way of doing things.
  There is no config file, i believe all configurations are written in <strong>.env</strong> file, but i really don't know why the session_driver and cache_driver is defaulted to memecached even after changing it in the <strong>.env</strong> and then ran <code>composer dump-autoload</code> ... Lumen :(</p>
  
  <p><strong>EDIT</strong>
  This is my <strong>.env</strong> file</p>
  
  <pre><code>APP_ENV=local
  APP_DEBUG=true
  APP_KEY=SomeRandomKey!!!
  
  APP_LOCALE=en
  APP_FALLBACK_LOCALE=en
  
  DB_CONNECTION=mysql
  DB_HOST=localhost
  DB_DATABASE=test
  DB_USERNAME=root
  DB_PASSWORD=
  
  CACHE_DRIVER=array
  SESSION_DRIVER=cookie
  QUEUE_DRIVER=database
  </code></pre>
  
  <p>I already have this line uncommented in my bootsrap/app.php</p>
  
  <pre><code> Dotenv::load(__DIR__.'/../');
  </code></pre>
  
  <p>My DataBase configuration works perfectly so the .env file is loaded
  quite alright.</p>
