I would like to ask if you can help me with this error while installing RoR on my mac machine running on a macOS 10.12 version.
Based on this guide https://gorails.com/setup/osx/10.12-sierra

It sounds like possibly one solution is:
I have same problem. And I fixed it by select Xcode 8 Command Line Tool in the Xcode 8. (current Xcode 7.3)
Which I found here: https://github.com/Homebrew/homebrew-core/issues/3604
Maybe try that?
Unfortunately I don't have an extra computer at the moment to install Sierra on so I'll only be able to give suggestions without testing things out myself.
