TypeError when installing yo closure

[robinchesterman]

Hi guys - new to Yeoman, so looking for the right place to ask questions. Apologies if this is not it.

I installed generator-closure because I'm interested in exploring Google Closure. That went fine, but yo closure comes up with an error:

...
create Gruntfile.js
create README.md
create LICENSE-MIT

TypeError: Cannot read property 'green' of undefined
