Unable to compile less file.

Used the python manage.py compilestatic command to compile the card.less file which is in the static folder of django project, getting this error

(venv) [swastik@manjaro eduBOT]$ python manage.py compilestatic

It is compling now, but don't provide the complete CSS like colors are not showing up and other things as well.

@swastkk I ran into the same issue. I believe this boils down to the location of the Less compiler changing, but I was able to work around this by setting an explicit executable setting in my settings.py:

STATIC_PRECOMPILER_COMPILERS = (
    (
        "static_precompiler.compilers.LESS",
        {
            "executable": BASE_DIR / "node_modules/less/bin/lessc",
        },
    ),
)
