[SOLVED] How to use SCSS in a rails 8 project?

How to use SCSS in a rails 8 project?

I just started a new Rails 8 (Ruby 3.4.1) project with the new propshaft asset pipeline and I can't get SCSS to work. I've tried adding the sassc-rails gem to my gemfile, like in my recent Rails 7 project, but when I run bundle install, I get an error message that looks life this :

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
An error occurred while installing sassc (2.4.0), and Bundler cannot continue.

In Gemfile:
  sassc-rails was resolved to 2.1.2, which depends on
    sassc

I've tried replicating anything related to style and file imports in my new app from my rails 7 app, but nothing worked for me. Any idea how to use SCSS in Rails 8 ?

Solution

Add these lines at your Gemfile and Procfile.

gem 'dartsass-rails' # Gemfile

css: bin/rails dartsass:watch # Procfile.dev
