Can any one help me to solve following error? this is my first experiment for node yeoman and backbone please help me..

I had the same problem and got it running.
There is a version conflict with compass and sass both of which are needed by the framework you installed via the yo command.

gem uninstall compass sass

gem install sass compass

Idea stolen from here. Why does "compass watch" say it cannot load sass/script/node (LoadError)?
