Answer 1

could be an old verison of yo installed

npm cache clean && npm upgrade -g yo

Answer 2

To be on the save I'd also update all involved tools: npm update -g npm yo bower grunt.

Sometimes bower can't download all dependencies at the first time and it's required to run bower install again.
