When installing the plugin qgis2web through the plugin manager on the qgis 2.99 nightly release I get the following error message. Does anyone know what I need to do to get it working. I've not seen an obvious corresponding issue on the github repo.

Couldn't load plugin 'qgis2web' due to an error when calling its classFactory() method 

ImportError: No module named 'PyQt5.QtWebKitWidgets'

    Did you check if you have PyQt5 installed?

  • I can run import PyQt 5 in the python console, but import PyQt 5.QtWebKitWidgets throws and error.

The missing module is 'PyQt5.QtWebKitWidgets' which can be installed on ubuntu as part of the 'python3-pyqt5.qtwebkit' deb package.

To check if it is already installed, and ensure it is available, the command is:

apt-cache policy python3-pyqt5.qtwebkit

Assuming it isn't installed, then it can be installed with:

sudo apt install python3-pyqt5.qtwebkit

@TomChadwin put me on the right track.

I don't know what distribution you are on, but this is likely to be the availability of QtWebkit, or its Python bindings. See if you can ensure they are installed.

  • Thanks Tom. Should this be as part of the qgis install, or should they be somewhere separate? When you say 'distribution' do you mean of qgis2web?

  • I believe he<s referring to your Linux distribution or your OS. It may be the case that Ubuntu/CentOS/etc. doesn't include the latest version of QtWebkit5 or include more recent Python bindings for it. This is particularly true for LTS distributions (e.g. Ubuntu Xenial or Debian Jessie). Commented Feb 23, 2018 at 16:55
  • Thanks! Slow going with QGIS on ubuntu so appreciate the help. I'm on Ubuntu Xenial, I installed QGIS with http://qgis.org/ubuntugis-nightly xenial main and http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu xenial main ppa repositories. So assumed they handled dependencies. How would I check for the QtWebKit5/it's python bindings?

    I didn't give details because I'm not much of a Linux user either. Your edit would have made it look as though I knew things I don't. Commented Feb 24, 2018 at 23:27

    @RoperMaps think of self-answering your question.
