title: yajra/laravel-datatables package - Class DataTablesServiceProvider not found
body: <p>I'm working on a project using Laravel as a framework.
  After creating all the migrations I need to use, I would like to begin with the implementation of the CRUD operation. Using the InfyOm library, with a few commands I can pull out a layout for my backoffice.
  The problem is, however, the use of the yajra library for the creation of datatables.
  Following GitHub's Guide, I'm coming to update my Composer and the latter gives me this type of error:</p>
  
  <pre class="lang-none prettyprint-override"><code>[Symfony\Component\Debug\Exception\FatalErrorException] Class 'Yajra\DataTables\DataTablesServiceProvider' not found
  </code></pre>
  
  <p>In <code>Composer.json</code> I have the following data:</p>
  
  <pre><code>    ...
      "php": "&gt; = 5.6.30",
      "laravel/framework": "5.4. *"
      "yajra/laravel-datatables-oracle": "~ 6.0"
      ...
  </code></pre>
  
  <p>While in <code>config/app.php</code> I have:</p>
  
  <pre><code>'providers' =&gt;
      ...,
      Yajra\DataTables\DataTablesServiceProvider::class,
  
  
  'aliases' =&gt; [
      ...,
      'DataTables' =&gt; Yajra\DataTables\Facades\DataTables::class,
  ]
  </code></pre>
  
  <p>Can you tell me why I have this exception? I tried to change the version of PHP, yajra and even Laravel without getting results.</p>
