I have not updated Homebrew in a few weeks. I updated today. Now, when I run brew doctor, I get this:

igordot commented 6 years ago

I was able to solve the issue. I think the problem was with the science tap (recently deprecated). When I removed it (brew untap homebrew/science), the error went away.

I am not sure if you want to consider the issue closed. There might be better ways to handle the error, such as making it more clear where it is coming from.

alyssais commented 6 years ago

I think we could use better messaging on this. I've seen a lot of user confusion about this error.

MikeMcQuaid commented 6 years ago

@alyssais Do you have a reproduction case?

alyssais commented 6 years ago

Ignore me, I misread the issue.

MikeMcQuaid commented 6 years ago

If you brew update do you still see this?

igordot commented 6 years ago

Correct, brew update did not fix the problem.

ilovezfs commented 6 years ago

@igordot he meant that you should try again, as we've released a new version of Homebrew with changes that may affect the behavior. Are you actually currently still able to reproduce the issue?

igordot commented 6 years ago

@ilovezfs I cannot reproduce the issue, but I was able to resolve it by untapping homebrew/science (see https://github.com/Homebrew/brew/issues/3721#issuecomment-359612223).

ilovezfs commented 6 years ago

@igordot right I saw that :) If you re-tap homebrew/science, does it come back?

igordot commented 6 years ago

I updated brew and went back to my previous taps.

Here are my updated taps:

caskroom/cask
homebrew/core
homebrew/science
homebrew/versions

This leads to brew doctor error:

Looks like the depends_on warning was resolved.

I just realized my previous comment may have been incorrect. Running brew untap homebrew/science did not solve the error. However, tapping the replacement (brew tap brewsci/science) does.

Curiously, brew tap brewsci/science generates many warnings:

To summarize, no error with these following taps:

brewsci/science

homebrew/versions

What does brew config now show?

MikeMcQuaid commented 6 years ago

@igordot Please run brew doctor --verbose --debug and paste the output here, thanks!

Can you run export HOMEBREW_NO_AUTO_UPDATE=1 temporarily and can you add p ref on line 363 of /usr/local/Homebrew/Library/Homebrew/formulary.rb and then rerun brew doctor --verbose --debug? Thanks!

byronformwalt commented 6 years ago

@MikeMcQuaid I followed your procedure and determined that on my machine, :rbenv is the offending value of ref on line 363.

I was able to resolve the issue by inserting the following line before line 363: ref = ref.to_s if ref.is_a? Symbol

apjanke commented 6 years ago

@igordot Triggering this might be dependent on the specific formulae you have installed. Could you post the output of brew ls for us?

When I removed it (brew untap homebrew/science), the error went away.

Given that seems to fix it and the rest of this is a mystery: closing this out. If @byronformwalt or others still have an unresolved issue here: please shout and I'll reopen. Thanks all!

byronformwalt commented 6 years ago

@Mike McQuaid

Will do. I don’t recall which formula caused the problem for me, but it was a simple fix. If it happens again, I’ll post here.

I ran into this issue as well. The patch above does hide the error for me.

The offending formula seems to be emacs. brew info emacs:

emacs: stable 25.3 (bottled), devel 26.0.91, HEAD
GNU Emacs text editor
https://www.gnu.org/software/emacs/
/usr/local/Cellar/emacs/25.3 (4,051 files, 119.6MB) *
  Built from source on 2017-09-18 at 08:54:52 with: --with-cocoa

brew cleanup emacs, which removed versions 24.5, 25.1, and 25.2, did not help.

Uninstalling emacs and reinstalling with brew cask install emacs as recommended did eliminate the error message. I don't yet know if this version meets my needs, but I'll try it out.
