5 months ago The release version of OpenSCAD is pretty old (its from 2021). This script requires features that are only in the development version. I will update the error message to make that clearer.
You can download that here - https://openscad.org/downloads.html#snapshots Sorry for the confusion, let me know if you are still having issues.
Without this fix the version is not checked correctly. The latest version ist 2021.1.
