So Sass and Less don’t change the functionality of CSS, as they are compiled into plain old CSS. What they do is make it easier to write and … Read more
Although using node.js version is recommended, you can install less as ruby gem: sudo apt-get install rubygems1.8 ruby1.8-dev sudo gem install rubygems-update sudo gem update rubygems sudo gem install less and than use lessc which is in /var/lib/gems/1.8/bin/lessc, so you may want to create symlink: sudo ln -s /var/lib/gems/1.8/bin/lessc /usr/bin/ or add ruby gems dir … Read more
