CodePudding user response：

Tailwind CSS for Rails is not compatible with SassC::Rails:

Tailwind uses modern CSS features that are not recognized by the sassc-rails extension that was included by default in the Gemfile for Rails 6. In order to avoid any errors like SassC::SyntaxError, you must remove that gem from your Gemfile.

Remove sassc-rails from your Gemfile, run bundle, commit the changes, and redeploy.
