If it's a brew cask problem please file this issue at https://github.com/Homebrew/homebrew-cask/issues/new/choose. If it's a tap (e.g. Homebrew/homebrew-php) problem please file this issue at the tap.
• [x] ran brew update and can still reproduce the problem?
• [x] ran brew doctor, fixed all issues and can still reproduce the problem?
• [x] ran brew config and brew doctor and included their output with your issue?

What you were trying to do (and why)

brew audit

What happened (include command output)

➜ brew audit
==> Installing or updating 'bundler' gem
Error: Unable to resolve dependency: user requested 'did_you_mean (= 1.2.1)'

What you expected to happen

Brew should install the required dependencies and run audit.

Step-by-step reproduction instructions (by running brew commands)

• Install Linuxbrew
• Run brew audit

This does not happen under macOS, therefore creating an issue here.

Thanks for the bug report, Werner. Could you please open this issue at https://github.com/Homebrew/brew? If you have access to macOS, it'd be helpful if you could try to reproduce the issue on macOS. Thanks!

Shaun, please re-read my report:

This does not happen under macOS, therefore creating an issue here.

It works under Homebrew/homebrew-core.

[slhck]

... that said, if this should still be reported under Homebrew, please let me know. Since this works fine under macOS, I think the error is here, specifically.

[sjackman]

Ah, sorry, I missed that.
Try…

rm -rf $(brew --repo)/Library/Homebrew/vendor/bundle
rm -rf $(brew --repo)/Library/Homebrew/vendor/portable-ruby
brew vendor-install ruby
brew style

[slhck]

That worked, thank you. Any idea what the underlying cause could be?

[sjackman]

The Ruby gems get confused, but no, I don't know why.

[sjackman]

Homebrew Ruby: 2.5.1 => /usr/bin/ruby2.5

brew vendor-install ruby install Ruby 2.3.7. My best guess would be a difference between these two versions of Ruby.

[slhck]

I looked at some similar messages from Homebrew-core, and the problem seemed to be caused by Gems being yanked (removed) from RubyGems. Since this is a no-repro and there's a workaround, I'm closing this issue. Thanks for your help!
