using boxes in python virtual environment

[dido77-arduino]

Hi

I would like to use the plugin in a python virtual environment, I am not successful at the moment.

I have setup the venv, cloned the repo and installed the requirements as needed

source $HOME/venv/bin/activate
cat ~/.config/inkscape/extensions/mightyscape-1.2/requirements.txt | sed '/^#/d' | xargs -n 1 pip install --upgrade --no-cache-dir (completed w/o errors)

I have also changed preferences.xml to use the virtual environment

       id="aboutextensions"
       python-interpreter="/home/username/venv/bin/python" />

When I start inkscape and I try any of the Boxes plugins, I receive the error

File` "/home/didomax/.config/inkscape/extensions/mightyscape-1.2/extensions/fablabchemnitz/boxes.py/boxes/scripts/boxes", line 24, in <module>
    import boxes
ModuleNotFoundError: No module named 'boxes'

I tried another plugin (Origami) and it worked w/o glitches.

Where am I missing a step

Thanks
Max

Hi,
can you ensure that boxes installed properly? Maybe it skipped installing due to some error reason?

you can check by

pip list installed | grep boxes

Hi @vmario89

actually no, it was not installed - I was assuming it was part of the requirements.txt, my bad.

I have now tried to install it, but it does not sound to me right

pip install boxes --no-cache-dir

And actually boxes.py is empty

cat venv/lib64/python3.10/site-packages/boxes/boxes.py

"""Main module."""

This is the full error

During handling of the above exception, another exception occurred:

    from affine import Affine
ModuleNotFoundError: No module named 'affine'

Which I do not understand, since python is able to find the libraries when called from command line.

Any clue what is going on?

hi, you actually installed the wrong boxes module: https://pypi.org/project/boxes/

please try to install like the following command:

pip install git+https://github.com/florianfesti/boxes.git

then run

boxes

the output will be

boxes.py

Generate stencils for wooden boxes.

Usage:
  boxes <generator> [<args>...]
  boxes --list
  boxes (-h | --help)
  boxes --version

Options:
  -h --help     Show this screen.
  --version     Show version.
  --list        List available generators.

[vmario89]

ps: i added the missing dependency in requirements.txt

[dido77-arduino]

Thanks for the prompt answer.

Some progress done, I can call boxes both from the command line and in the python (virtual) environment

$ boxes.py

Generate stencils for wooden boxes.

Usage:
  boxes <generator> [<args>...]
  boxes --list
  boxes (-h | --help)
  boxes --version

Options:
  -h --help     Show this screen.
  --version     Show version.
  --list        List available generators.

and

Python 3.11.7 (main, Jan  7 2024, 01:05:16) [GCC 13.2.1 20231216] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import boxes
>>> 

However, I get the very same error as in the previous post when trying to run the extension within inkscape. My preferences.xml

<group
     id="extensions"
     org.inkscape.output.png.inkscape.png_bitdepth="99"
     org.inkscape.output.png.inkscape.png_compression="6"
     org.inkscape.output.png.inkscape.png_antialias="2"
     python-interpreter="/home/didomax/venv/bin/python"

I do not know anymore where to look for issues...

looks like i will have to check it myself when using venv (actually never tried). Which OS are you running? Linux, Windows, ... ?

[dido77-arduino]

Gentoo Linux with python 3.11. Thanks Max 9 Feb 2024 09:07:11 Mario Voigt ***@***.***>:

i tested the thing with venv and it can confirm the failure. but good news: most of plugins work really well with venv. i will change mightyscape documentation to use venv mainly because it does not mess with system libraries at all
