FYI: Certain functionalities don't work on the latest version of openlayers

I was having issues with placing a marker, like this: https://rawgit.com/allenhwkim/react-openlayers/master/app/index.html#/custom/marker-style

I used the command npm install openlayers with no luck — map didn't show and I got an error with Openlayers.

Then I tried npm install [email protected] and now it works.

Just a heads up in case anyone has a similar problem.
