title: Can't import PyQt5.QtWebEngineWidgets
body: <p><br>
  I'm trying to make an vocabtrainer for myself to get better in english, cause I suck. To achieve this, I'm trying to make a GUI with PyQt5 to expand my programming experience too :). But somehow I can't import the <code>QtWebEngineWidget</code>...<br><br>
  This is my code:</p>
  
  <pre class="lang-py prettyprint-override"><code>import PyQt5.QtWidgets as pyqtW
  import PyQt5.QtGui as pyqtG
  import PyQt5.QtCore as pyqtC
  from PyQt5.QtWebEngineWidgets import *
  
  import sys
  
  
  class VocabTrainer:
  
      def __init__(self):
          self.main = pyqtW.QApplication([])
          self.window = pyqtW.QWidget()
  
          self.prepareWindow()
  
          sys.exit(self.main.exec_())
  
      def prepareWindow(self):
          """
          Set's the attributes of the window.
          """
  
          # window settings
          self.window.resize(250, 100)
          self.window.show()
  
      def openPons(self):
          """
          Opens the website of pons to be able to translate words.
          """
          pass
  
  test = VocabTrainer()
  </code></pre>
  
  <p>My IDE (PyCharm) warns me that it can't find the reference of <code>PyQt5.QtWebEngineWidgets</code> and if I run this code, I'll get this error message:</p>
  
  <pre class="lang-py prettyprint-override"><code>Traceback (most recent call last):
    File "/A/little/path/VocabTrainer.py", line 12, in &lt;module&gt;
      from PyQt5.QtWebEngineWidgets import *
  ImportError: libQt5Quick.so.5: cannot open shared object file: No such file or directory
  
  Process finished with exit code 1
  </code></pre>
  
  <p>I've installed the modules with the following commands:</p>
  
  <pre class="lang-py prettyprint-override"><code>pip install pyqt5
  pip install pyqtwebengine
  </code></pre>
  
  <p>I've also tried to reinstall the modules but without success.<br></p>
