I'm on 10.13.6, and when I run brew doctor I'm now seeing the following warning:

Warning: Ruby version 2.3.7 is unsupported on 10.13. Homebrew
is developed and tested on Ruby 2.3.3, and may not work correctly
on other Rubies. Patches are accepted as long as they don't cause breakage
on supported Rubies.

2.3.7 is the system ruby on 10.13.6, so this shouldn't be shown.

Doctor shows only the above warning.

$ brew --config

We need a new portable Ruby then.

There's no new tag yet, but it'll be fixed for you once that happens.

[chdiza]

Works, thanks :)

I confess I'm not really sure what that doctor check is trying to find. It looks like it will only yell when the system ruby is either less than the portable ruby or greater than the portable ruby. In the former case, there's no need for the doctor warning because the appropriate portable ruby gets automatically and immediately poured. In the latter case, the content of the warning is misleading and makes for bad UX, particularly for brand-new installs.

Unless there is a real risk that someone has manually replaced their system ruby with something newer, I suggest changing the warning message.

@chdiza People can (and do) override Homebrew to use a non-system-or-portable Ruby and things go 💥.
