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.

从您的 Gemfile、运行 bundle 中删除 sassc-rails，提交更改，然后重新部署。
