problem:
[email protected] depends on [email protected] [1]
[email protected] is not compatible with node >= 0.12 [2]

solution:

1. upgrade grunt-sass to the lastest version (today: [email protected]) [worked for me]
2. downgrade your node to 0.10.38. [didn't try]

[1] https://www.npmjs.com/package/grunt-sass
[2] sass/node-sass#1001

Other solution, that has also worked for me, was use the latest version of this project instead of the current release version (v0.3.5) installed by default.
Since the current version already use a new version of grunt-sass, your next project will not be affected with this issue. [1] But maybe can affected by other problems if master branch isn't stable. [2]

• Find out where your node packages are installed. (/usr/local/lib/node_modules if you are using osx with brew)
• Remove the generator-backbone folder.
• Clone this project.
• Open the cloned project folder.
• Install all dependencies with: npm install
• And run yo backbone again!
