Uncaught TypeError: Cannot read property 'any' of undefined

Keep on getting this issue:

When I stripe down the demo version all the way until there's only the BasicExample component left. It's still works but I do get the same error in the console. Upside of this stripped demo version compared with mine is that it doesn't break.

So I've tried the demo locally. But can't find where this issue is coming from.
Is this a known issue or are there more dependencies that I should take in account?

not compatible with react v.16

I've opened a PR to fix this, please take a look. In case this PR isn't seen, I've created another npm package which with these changes so it can be used (https://www.npmjs.com/package/touch-position-react). Right now if this npm package is included on an import, upon start up it throws errors because PropTypes needs a separate import + npm install of 'prop-types' as of React 15.5. Also using React.createClass was deprecated in React 16 and needs a separate require statement + npm install of 'create-react-class' to be used.
