Still fails and appears not to work with python 3

Googling results in https://github.com/sass/node-sass/issues/2877

and the following warning https://www.npmjs.com/package/node-sass?activeTab=readme

Warning: LibSass and Node Sass are deprecated. While they will continue to receive maintenance releases indefinitely, there are no plans to add additional features or compatibility with any new CSS or Sass features. Projects that still use it should move onto Dart Sass.

I have made a pull request for a potential fix for the python 3 issue, by swapping node-sass (deprecated) to sass.

Hello can you please share where & all we need to swap node-sass with sass ? to install using python 3.
