3. Now :code:`boxes` and :code:`boxesserver` can be runned like other commands
and the Inkscape extension should be available.
Troubleshooting
...............
When using the Inkscape extension something like the following error
might occur:
::
Traceback (most recent call last):
File "/Users/martin/.config/inkscape/extensions/boxes", line 107, in <module>
main()
File "/Users/martin/.config/inkscape/extensions/boxes", line 47, in main

ImportError: dlopen(/Applications/Inkscape.app/Contents/Resources/lib/python2.7/site-packages/lxml/etree.so, 2): Symbol not found: _PyBaseString_Type

This is because Inkscape on macOS ships its own version of Python 2.7 where
:code:`lxml` and other dependencies are missing.
A workaround is to edit the file at
:code:`/Applications/Inkscape.app/Contents/Resources/bin/inkscape`.
At line 79 there should be following code:
.. code::
export PYTHONPATH="$TOP/lib/python$PYTHON_VERS/site-packages/"
which needs to be changed to
.. code::
#export PYTHONPATH="$TOP/lib/python$PYTHON_VERS/site-packages/"
This forces Inkscape to use the Python version installed by Homebrew which
has all the necessary dependecies installed.
Note: This might break other extensions. In this case simply change the line
back and restart Inkscape.
