    Which version of PyQt5 are you using?
    It doesn’t work with PyQt5 5.7.1 an newer versions

      Just tested with Python 3.6.1 and PyQt5 5.8.2-2 on Manjaro Linux, it runs fine.
      PyQt5 has the option to include WebKit, this needs to be done at compilation step of the framework. Sometimes versions of PyQt5 are distributed that don’t include WebKit. You could recompile PyQt5 to include WebKit or use a redistributable on another OS like Manjaro.
