Updated NPM - then Yeoman-Polymer; Now throwing bad error

Just an FYI, I have reported this to npm/issues first - just wanted to give you a heads up of something crazy that went down. Just updated my NPM with npm updated -g and npm updated -g npm. Additionally, after that I updated all my yo-generators and they are all fine except the polymer one. :(

Getting this error preventing me from even using it:
