Hi @igorescobar, I also have this problem. I run `sudo npm install -g automated-screenshot-diff` on my os `ubuntu 16.04` `node v6.10.1` `npm v3.10.10` Thanks for helping

I also error the same you as well. when run `yslow --help` ``` /usr/local/lib/node_modules/yslow/bin/yslow:16 doc = require('jsdom').jsdom(), ^ TypeError: require(...).jsdom is not a function at Object. (/usr/local/lib/node_modules/yslow/bin/yslow:16:28) at Module._compile (module.js:570:32)...

@davidfavor I still got that error the same.
