Please follow the general troubleshooting steps first:

• [Yes] Ran brew update and retried your prior step?

Anushas-MacBook-Pro:local varun$ brew update
Already up-to-date.

• [Yes] Ran brew doctor, fixed as many issues as possible and retried your prior step?

Try:

cd /usr/local/Library/Taps/homebrew/homebrew-core && git fetch && git reset --hard origin/master

Note: Will remove any custom changes you've made to formulae in homebrew/core, if you've made any.

[UniqMartin]

@DomT4 The problem is the user isn't even able to tap that repository, so the path probably doesn't exist. All of the formulae pointed out in the error messages have in common that they have a url with :using => :cvs. Not really sure what is going on, but this smeels like a bug in some recent brew changes to me. Unfortunately, I cannot reproduce the problem locally.

Oops, I completely forgot Mike's changes around tap readall execution went in the other day. Stupid moment, sorry.

[vnagavarun]

this is the error i am getting now

Anushas-MacBook-Pro:bin varun$ cd /usr/local/Library/Taps/homebrew/homebrew-core && git fetch && git reset --hard origin/master
-bash: cd: /usr/local/Library/Taps/homebrew/homebrew-core: No such file or directory
Anushas-MacBook-Pro:bin varun$ ls -ltr /usr/local/Library/Taps/homebrew
ls: /usr/local/Library/Taps/homebrew: No such file or directory
Anushas-MacBook-Pro:bin varun$ ls -ltr /usr/local/Library/Taps
Anushas-MacBook-Pro:bin varun$

so there is no directory called homebrew in taps

[UniqMartin]

@vnagavarun Thanks, that contained crucial information! I think the bug should be fixed now. Can you brew update, try again installing git, and report back whether this worked?

For those interested: The bug was only affecting macOS prior to 10.9 and only if neither Xcode nor CLT was installed. More details in the commit message of ccb1193. Crucial to understanding was this line in dependency_collector.rb and the fact that CVS-using formulae were affected.

[vnagavarun]

thanks a lot. it works now
