WaterCard maker for 
.
Examples can be seen here.
You need Python>=3.12.0 and poetry>=2.0.0.
After cloning the repo run poetry install in this directory.
It's OK if you're not a poet.
You can also use requirements.txt.
Oh ok, so you can run pip install -r requirements.txt.
Should you encounter any issues just use a search-engine of your choice!
Just run poetry run python -m WaterCard and answer the questions.
Then just use python -m WaterCard or any other equivalent and answer the questions.
My guess is that a library required by WeasyPrint is missing.
Copy the error message and paste it into a browser of your choice.
There should be a thread explaining the required steps to install the library.
Note
If you're helpless and on Windoof and have a error message like OSError: cannot load library 'libgobject-2.0-0': error 0x7e. Additionally, ctypes.util.find_library() did not manage to locate a library called 'libgobject-2.0-0' try installing the GTK3 runtime *no warranty
This is what an old version of WeasyPrint suggests at least...
If that doesn't work for you just try to stick to the latest documentation of WeasyPrint.
