I'm not able to create QR codes in Inkscape.

I try to create a QR code in Inkscape by going through these menus:
Extensions -> Render -> Barcode -> QR Code

But, when I click "Apply" to create the QR code, Inkscape prints an
error message like this:

------
Traceback (most recent call last):

    from lxml import etree
ModuleNotFoundError: No module named 'lxml'
------

Any ideas?

Wrap inkscape with GUIX_PYTHONPATH and 'python-lxml' as an input.  Or
simply install python-lxml (and python) in your user profile.
