The 'rake --trace assets:precompile' command gives the following error:
rake aborted!
Sass::SyntaxError: Invalid CSS after "...ules: $modules ": expected "}", was "!global;"

The error appears to come from line 13 of 'foundation-rails-5.5.0.0/vendor/assets/stylesheets/foundation/_functions.scss'

The SASS syntax looks fine to me, and compiles without error provided I have made no edits to the generated 'app/assets/stylesheets/foundation_and_overrides.scss.' If I make the smallest change to that file, such as the following, the compilation error occurs.

Environment is Rails 4.0.8, foundation-rails 5.5.0.0
The foundation-rails gem has set the lower bounds on their Sass dependency to >= 3.2.0, but are using a Sass 3.3 feature (the !global flag). You'll need to specify a dependency for 3.3 for your project.
I also recommend submitting a bug report to the maintainers of foundation-rails.
