Then the following error occurs at the final stage

Ruby Sass has reached end-of-life and should no longer be used.

* If you use Sass as a command-line tool, we recommend using Dart Sass, the new
  primary implementation: https://sass-lang.com/install

* If you use Sass as a plug-in for a Ruby web framework, we recommend using the
  sassc gem: https://github.com/sass/sassc-ruby#readme

* For more details, please refer to the Sass blog:

It seems to be a note about what you are using. When I try to translate with google

Decrypt the error

That said, I am using a different command line tool, so this time it seems to be a caution that occurred when using sass with the second Rais, when I jump to github as described and check the README Correspondence was written.

solution

Gemfile

gem 'sassc'

It seems that you should describe here. After that, bundle install was completed successfully.
