Brew: No formulae at all were found in taps

[jleeothon]

• [x] If Homebrew was updated on Aug 10-11th 2016 and brew update always says Already up-to-date. you need to run: cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update.
• [x] Ran brew update and retried your prior step?
• [x] Ran brew doctor, fixed as many issues as possible and retried your prior step?
• [x] Confirmed this is a problem with Homebrew/brew and not specific formulae? If it's a formulae-specific problem please file this issue at https://github.com/Homebrew/homebrew-core/issues/new

I can basically not install any formula at all. Something like brew install git will fail with:

$ brew install git
Error: No available formula with the name "git" 
==> Searching for a previously deleted formula...
Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.

These formulae were found in taps:

To install one of them, run (for example):
  brew install homebrew/fuse/gitfs

Output for brew tap is:

$ brew tap
homebrew/core
homebrew/dupes
homebrew/php
homebrew/versions

Not sure if related (?), my Cellar is empty:

n$ ls -la /usr/local/Cellar
total 0
drwxrwxr-x+  2 othon  brew   68 Mar 23 17:42 .
drwxrwxr-x  13 othon  brew  442 Mar 23 17:42 ..

Is there any further piece of information I can provide? Any ideas why I might be unable to find any formulae at all? Thanks!

Core tap ORIGIN: https://github.com/Homebrew/brew

This should be https://github.com/Homebrew/homebrew-core. Not sure how that would happen.

[jleeothon]

@bfontaine is the right command:

brew tap homebrew/core https://github.com/Homebrew/homebrew-core

[bfontaine]

No, it won’t do anything because homebrew/core is already tapped (and you can’t untap it).

Something like this should work:

cd $(brew --prefix)/Library/Taps/homebrew && rm -rf homebrew-core && brew tap homebrew/core

[jleeothon]

In my computer, $(brew --prefix)/Library doesn't exist (i.e. /usr/local/Library) 😅

[jleeothon]

Ah, it's probably $(brew --prefix)/Homebrew/Library/Taps/homebrew : )

[MikeMcQuaid]

rm -rf /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core; brew update

[jleeothon]

Using the right directory, it worked! Now I just have to set right the rest of my environment after this mess. Thanks you all!

Shall we close this ticket?
Any ideas on how this could have happened?
Is this kind of situation something that brew doctor could as well check for?

[MikeMcQuaid]

Closing this as I've opened a new PR to add this to brew doctor in https://github.com/Homebrew/brew/pull/2398. Thanks for the report!
