              - Ensure a recent xcffib is installed (pip install 'xcffib>=0.5.0')
              - The pip cache is cleared (remove ~/.cache/pip, if it exists)

                  pip install --no-deps --ignore-installed cairocffi

                or

                  pip uninstall cairocffi && pip install cairocffi
