sass command not working

I have something stupid: I installe开发者_Go百科d haml with bundle and did a "bundle install". The gem is installed, it is in the local gem list. When I then do "sass --watch style.scss:style.css" then I get: "'sass' is not recognized as an internal or external command". What am I doing wrong here? Thanks for your reply!

To execute commands from the gems in the bundle, you can use bundle exec. In your case e.g. bundle exec sass --watch style.scss:style.css.

I installed sass with:

$ sudo gem install sass

Then you can just run:

$ sass --watch ftw.scss:ftw.css
