Are you using Windows? I've deleted all my global npm packages, cloned my repo and reinstalled all npm packages to have a clean environment and it's working like a charm. But I'm on linux, Xubuntu 16.04.

Update: on Windows it is working but coverage summary lists "0/0" on every line... I don't know why

Somehow I managed to clone it down incorrectly. It works fine now. I'm running OSX El Capitan.

Code update: removed cross-env dependency, moved babel configuration to webpack.config.js

i'm closing this in favor of #53
