I got the same error as above, but it was not due to a case issue. It ended up being due to a combination of things. I had two ruby version managers installed- rvm and rbenv- and I was using an old gem installer. I had to uninstall rvm (How can I remove RVM (Ruby Version Manager) from my system?) and reinstall rbenv (brew reinstall rbenv)and upgrade to the lastest version of ruby. Then I had to update rubygems (gem update --system). Then, reinstalled all gems and a reboot and everything was fixed.

Essentially, my ruby manager was pointing to an old version of ruby and using an outdated version of the gem installer (2.2.0). You might be able to fix things with just an upgrade to rubygems.

It took me a day and a half to get this resolved. Hopefully, this will save someone some time and frustration.
