Based on the comment from Python package install failing - Stack Overflow (I duplicate posted) It sounds like the issue is actually associated with a lack of a windows build for the rpy2 package. 

I need to test installing from an alternative mirror as mention in the package GitHub issues page Can't install rpy2 · Issue #390 · rpy2/rpy2 · GitHub
