brew install failed one time with "Homebrew must be run under Ruby 2.3!" on Ruby 2.4, now works fine
Running brew install colordiff gave me an error message related to #3240, but only once. I am running Ruby 2.4, but #3240 is checking for minor version less than 3. I'm not sure how I saw this error, as the code looks like it would allow for 2.4.
Below is the exact sequence of commands I used.
> brew install colordiff

I am running Ruby 2.4
Homebrew always uses the system Ruby, so it likely started with Ruby 2.0.0, installed the vendored Ruby 2.3.3, but then didn't use the vendored Ruby the first time.
Can you reproduce the error if you remove /usr/local/Homebrew/Library/Homebrew/vendor/portable-ruby?

Would this explain why Travis builds for OSX fail? https://travis-ci.org/szeck87/atom-beautify/jobs/286285106

Hi everyone! This is María from Travis CI -
As @szeck87 mentioned, we're seeing a similar behaviour in our macOS environment on macOS builds https://github.com/travis-ci/travis-ci/issues/8552#issuecomment-335430374
Seems that current workarounds would be:
removed- running
brew updatebeforebrew install package_name
Does this help? Thank you!

This was fixed in Homebrew 1.3.4, so if you are on >= 1.3.4 now, you can safely ignore this error. For Travis, refer to the workaround above.

@MariadeAnton The better fix would be if Travis CI could prioritise updating the Homebrew on your base images (basically: run brew update, create a new image). I've removed one of your suggestions because we intentionally don't want people to just disable auto-updating because then they will never turn it back on and file bugs to us based on old Homebrew versions. Thanks!

@MikeMcQuaid thank you for explaining - that makes sense!
These are workarounds while we update our long-term support macOS images, we'll stick to brew update in the meantime :)

OK, running brew update before any installs worked. Not to sidetrack this issue, but @MariadeAnton is there an issue in https://github.com/travis-ci/travis-ci/ I can comment on about updating images? Updating Homebrew takes the longest and certainly doesn't help the number of backlog OSX builds, while updating the images frequently would reduce that significantly.

@javadba Could you please open a new issue and fill out the issue template as much as you can.
