Error when building: discourse does not support compiling scss/sass files via sprockets

This article helped for me Guide to Setting Up Discourse Development Environment - Windows 11

It appears that you should run this:

DISCOURSE_HOSTNAME=localhost UNICORN_LISTENER=localhost:3000 bin/ember-cli -u

it starts:

  1. rails server
  2. sidekiq
  3. ember-cli

And discourse becomes available at localhost:4200

It’s a shame that this is not mentioned in DEVELOPMENT-OSX-NATIVE nor in DEVELOPER-ADVANCED.md
