For those still having this issue I recently, setup a new laptop with react-slingshot.

https://gist.github.com/kwelch/618a156d9aa7e1702f6b3cd2e6abc5b2 (The prop-types part has been fixed with the recent merge of the React 16 upgrade)

The believe I ran across the same issue as others in this thread and installing watchman fixed the issue completely.

Hey @DaneTheory and @coryhouse myself and another developer were receiving this error as well. We found out that watchman is required / a dependency, but not annotated in your docs. After running brew install watchman the build works as intended.
