About installation of Sass 3.3

Current version of my environment.

• Sass 3.2.10 (Media Mark)
• Compass 0.12.2 (Alnilam)

I know Compass doesn't work on Sass 3.3. But... http://stackoverflow.com/questions/22427567/is-sass-3-3-3-compatible-with-compass

Maybe it works with '--pre' option install.

$ gem install compass --pre

If it won't work unfortunately, let's back to old version. http://stackoverflow.com/questions/17026441/how-to-install-a-specific-version-of-a-ruby-gem

$ gem install sass -v 3.2.10
$ gem install compass -v 0.12.2
