title: Fatal error: Call to undefined method GuzzleHttp\Client::request() with Guzzle 6
body: <p>I'm using Guzzle 6 with Laravel 5.2. </p>
  
  <p>I'm trying to access a simple internal API:</p>
  
  <pre><code>use GuzzleHttp\Client;
  
          $client = new Client(['base_uri' =&gt; getenv('URL_BASE').'api/v1/']);
          $response = $client-&gt;request('GET', 'tournaments');
  </code></pre>
  
  <p>And I get this message:</p>
  
  <pre><code>Fatal error: Call to undefined method GuzzleHttp\Client::request()
  </code></pre>
  
  <p>When I see the <a href="https://github.com/guzzle/guzzle/blob/master/docs/quickstart.rst">docs</a>, it says: </p>
  
  <pre><code>$client = new GuzzleHttp\Client(['base_uri' =&gt; 'https://foo.com/api/']);
  </code></pre>
  
  <p>But PHPStorm cannot resolve GuzzleHttp</p>
  
  <p>What should I do to make it work???</p>
