Version: react-draggable 2.2.0
Browser: Google Chrome Linux 51.0.2704.106 (64-bit)
Error: Cannot read property 'getComputedStyle' of undefined
Source of error: https://github.com/mzabriskie/react-draggable/blob/ac269435565fe584f0409345dcb79e8f5b682828/lib/utils/positionFns.es6#L29
Looking a few lines up from the source of the error, I think that changing
const ownerWindow = node.defaultView;
to
const ownerWindow = ownerDocument.defaultView;
might fix the problem. I've never used defaultView before though, and I'm not sure what is trying to be achieved with it, so take that with a pinch of salt.
I have no problems with react-draggable 2.1.2.
