title: CKEditor 5 throws Cannot read property 'create' of undefined in Angular6 project
body: <p>I've created a project using JHipster and trying to create a WYSIWYG rich text editor using CKEditor 5. I've done the below steps by using the following <a href="https://www.npmjs.com/package/@ckeditor/ckeditor5-angular" rel="nofollow noreferrer">link</a> to create an editor.</p>
  <ol>
  <li><p>npm install --save-dev @ckeditor/ckeditor5-angular</p>
  </li>
  <li><p>npm install --save-dev @ckeditor/ckeditor5-build-classic</p>
  </li>
  <li><p>Imported @ckeditor/ckeditor5-angular and added in imports in my module.js</p>
  </li>
  <li><p>Imported @ckeditor/ckeditor5-build-classic and created a variable public Editor: ClassicEditor; in my component</p>
  </li>
  <li><p>Used following code in html</p>
  
  </ol>
  <blockquote>
  <p>Blockquote</p>
  </blockquote>
  <pre><code>&lt;ckeditor [editor]=&quot;Editor&quot; data=&quot;&lt;p&gt;Hello world!&lt;/p&gt;&quot;&gt;&lt;/ckeditor&gt; 
  </code></pre>
  <p>When I go to the page I added throws the following error which I got it from the browser developer tools console.</p>
  <pre><code>ERROR TypeError: Cannot read property 'create' of undefined

  <p>I'm just wondering if that's an issue with CKEditor 5 or did I miss any steps?</p>
