# If you arrived here because sassc is not in your project's Gemfile,
# the issue here is that the release of the better_errors gem
# is supposed to contain the compiled CSS, but that file is missing from the release.
# So better_errors is trying to build the CSS on the fly, which requires the sassc gem.
#
# If you're developing the better_errors gem locally, and you're running a project
# that does not have sassc in its bundle, run `rake style:build` in the better_errors
# project to compile the CSS file.
