sudo apt-get install ruby sudo apt-get install ruby-dev sudo gem install susy -V sudo gem install compass --pre -V sudo gem lnstall breakpoint -V
- The current version of Susy uses a higher version of Sass than Compass, so the corresponding Compass version has to be a prerelease (–pre).
- The installing process is slow and it feels better to print it out (-V).
- You may have to run “compass watch” with sudo (issue 1497).
- An alternative RubyGems source that is close to your location might help.
