Please fill out the issue checklist below, and provide all of the requested information.

Please always follow these steps:

[x] Confirmed this is a problem with running a brew command and not brew installing or the post-install behaviour of one or more formulae? If it's a formulae-specific problem please file this issue at the relevant tap e.g. for Linuxbrew/homebrew-core https://github.com/Linuxbrew/homebrew-core/issues/new
[x] Ran brew update and retried your prior step?
[x] Ran brew doctor, fixed all issues and retried your prior step?
[x] Ran brew config and brew doctor and included their output with your issue?

To help us debug your issue please explain:
brew update gives:

Warning: git 2.15.1 is already installed
Error: Git must be installed and in your PATH!

I tried remove git by brew uninstall --force git and reinstall using brew install git and it ended up the same.
Note that I have to install linuxbrew in /scratch/.linuxbrew and symlink that directory to /home/linuxbrew/.linuxbrew but other than that there's nothing special in my linuxbrew setup. Also, I noticed there was a homebrew issue: https://github.com/Homebrew/homebrew-core/issues/3029 and I'm not sure if it's related because linuxbrew has been working fine until a recently.
Here's the output from brew config:

Possibly related: I reproduced the same on High Sierra, and after performing the HOMEBREW_NO_ENV_FILTERING=1 hack, I managed to make some progress; then I noticed the following message:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

...and so I am wondering if — because I need to update Xcode — the env-filtering code is perhaps aborting part-way-through, and somehow corrupting the PATH which Brew uses, and then failing to find Git?

UPDATE: it appears to have been fixed, after doing:

export HOMEBREW_NO_ENV_FILTERING=1
xcode-select --install
brew update
brew upgrade

...and then starting a new Terminal shell to try a fresh environment

Well that certainly seems contradictory.

Git: N/A

That's not good.

That's a weird one. I tried to reproduce it myself by removing the system-installed /usr/bin/git and installing the brewed git. brew happily found git at $HOMEBREW_PREFIX/opt/git/bin/git, so I'm not sure why yours doesn't. Here's the code for Utils.git_available?
https://github.com/Linuxbrew/brew/blob/master/Library/Homebrew/utils/git.rb#L30

    @git ||= quiet_system HOMEBREW_SHIMS_PATH/"scm/git", "--version"

All it does is run $(brew --repo)/Library/Homebrew/shims/scm/git --version, and from your output above, that returns…

git version 2.15.1

My best guess is that PATH is set differently inside brew. Any chance that you have the environment variable HOMEBREW_DEVELOPER set?
Please report…

brew irb <<<'[which("git"); Utils.git_available?, Utils.git_path, Utils.git_version]'
HOMEBREW_NO_ENV_FILTERING=1 brew irb <<<'[which("git"); Utils.git_available?, Utils.git_path, Utils.git_version]'
HOMEBREW_GIT=$(brew --prefix)/opt/git/bin/git brew irb <<<'[which("git"); Utils.git_available?, Utils.git_path, Utils.git_version]'

No, I confirm that HOMEBREW_DEVELOPER is never set. Here are the outputs:

Thanks! It works!

I hope you will find the real problem being this, though.

avetisk on 14 Dec 2017

Can you test whether PR https://github.com/Linuxbrew/brew/pull/537 resolves your issue without setting HOMEBREW_NO_ENV_FILTERING?

cd $(brew --repo)
git fetch origin pull/537/head:pr537
git checkout pr537
unset HOMEBREW_NO_ENV_FILTERING
brew irb <<<'[which("git"), Utils.git_available?, Utils.git_path, Utils.git_version]'
git checkout master

sjackman on 15 Dec 2017

@sjackman: it works :)

Output from the brew irb:

[#<Pathname:/home/linuxbrew/.linuxbrew/bin/git>, true, "/home/linuxbrew/.linuxbrew/bin/git", "2.15.1"]

BTW, I think there's a typo in your snippet (s/534/537/g).

I'm experiencing the same issue. I had to use, as suggested, HOMEBREW_NO_ENV_FILTERING=1.

Woops, yep. I've corrected it above for others.

I have the same issue. The solution in PR #537 does not work for me. The workaround HOMEBREW_NO_ENV_FILTERING=1 does work.

Same issue on Elementary OS, and works fine on Antergos.

What is the best way to update brew to get these new fixes? Do I need to uninstall brew and reinstall? "brew update" doesn't do anything it seems.

(well, I put the export work around above, and did brew update, and that worked...)

@alecmroo Is there a particular reason that you're using Linuxbrew/brew on macOS? Although it's officially supported, most macOS users would use Homebrew/brew instead. Linuxbrew is a fork of Homebrew that adds support for Linux.

@alecmroo

THX your 4 Step's fixed it for me too...

mircsicz on 11 Jan 2018

I just got bit w/ this bug myself.

537 doesn't work

544 appears to work

545 appears to work

HOMEBREW_NO_ENV_FILTERING=1 appears to be the only solution that works on master

@nega0 Please report the output of…

@sjackman I will, but unfortunately it will have to wait as linuxbrew is not currently in the same state. In the meantime #565 may have some info. (Again, not exactly the same state.)

There's the auto-install of portable-ruby that I didn't see in #566.

Mojave macOS has this problem. Unable to update brew.

@bisherbas I had to reinstall xcode-select with xcode-select --install, but I was able to run brew update after I did.

julienroger on 25 Sep 2018

To me, this was fixed after I xcode-select --install

@bisherbas @julienroger @niufei8888

As stated by @sjackman, this thread is relevant to Linuxbrew and not Homebrew. Xcode is Mac software not Linux software. Anything that references MacOS or xcode should be included in a respective Homebrew thread.

Cheers,
James

Same here. xcode-select --install fixed the issue. @sjackman Thanks for the reminder. Totally missed that.

eminphi on 1 Oct 2018

Let's close this. Please report problems on mac to https://github.com/Homebrew/brew.
This repository is for Linux only. Thanks!
