title: Laravel - Can't change default cache driver
body: <p>I'm trying to change cache driver from <strong>file</strong> to <strong>redis</strong> or <strong>apc</strong>, but everytime when I said <code>dd(\Cache::getDefaultDriver());</code> it gives me that "file" as default cache driver.</p>
  
  <p>I cleared config and stored cache, but it still continue..</p>
  
  <pre><code>php artisan config:cache
  php artisan cache:clear
  </code></pre>
  
  <p>in my config/cache.php</p>
  
  <pre><code>'default' =&gt; env('CACHE_DRIVER', 'redis'),
  </code></pre>
  
  <p>What should I do ? I'm working on local and my laravel version is 5.6</p>
