Not really sure what I’m doing wrong here? I’ve set the correct Ruby version (2.2.5) and cleaned all generated files.

Thanks for the ideas! The following combo worked for me (64/64 suites passed ok):

  • blowing away the entire check out, re-clone and build from scratch.
  • create a new Ruby install (i.e. kill your 2.2.5 install and re-install)

Since I built difference-of-squares, I wonder if there was some weird git-invisible difference hanging around. That or my rvm-managed 2.2.5 was weirded up somehow. We’ll see if this setup continues to work 🤞
