  <p>When I access the application, I get the below error:</p>
  
  <blockquote>
    <p>Fatal error: Class 'Locale' not found in
    ./vendor/zendframework/zendframework/library/Zend/I18n/Translator/Translator.php
    on line 220</p>
  </blockquote>
  
  <p>I haven't tried installing <code>Doctrine</code> as suggested (because I don't want to use Doctrine in the end).</p>
  
  <p><strong>Does someone know how to fix this issue?</strong></p>
