Rails: Why is bundle install frozen up by sassc 2.4.0

Is there a problem with sassc version 2.4.0 and rails 6. I changed the version in the Gemfile to 2.1.0 and now it install fast and don't stucks on docker build.

Using an older version of sass solves the issue. I advise changing 6 to 5.1.0 in the Gemfile. This file will be located in your rails folder (the name you used when creating a new rails)

I think Rails 6 is not compatible with Sass 6.0.0's dependencies for some reason.
