Fixing that brings up another error.

I'm using version 3.1.0, which lists a dependency of "jsdom": ">=0.2.10". That may be too permissive since jsdom's current version in my yslow's node_modules directory is set at 5.0.1!
Perhaps an explicit pin to the last 3.x release for jsdom would be the best way to fix this?
