Error: 'git' must be installed and in your PATH!

[jhnworks]

Though having the latest git version
[ @ ~]$ which git
/usr/local/git/bin/git
[ @ ~]$ git --version
git version 2.7.0

and, running "brew upgrade" results in
[@~]$ brew upgrade >> /tmp/brew.upgrade.txt
Error: Please update your system Git.
Minimum required version: 2.7.0
Your Git version: ...

make: *** [all] Error 2

[ @ ~]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.9 (Maipo)

How does go about resolving this.

[carlocab]

Do

export HOMEBREW_DEVELOPER=1
export HOMEBREW_GIT_PATH=/usr/local/git/bin/git

As suggested by the HOMEBREW_DEVELOPER flag, this isn't really a fully supported use case, since we expect Git to be found in a standard system path.

Even after setting this -
[ @ ~]$ brew --version
Homebrew 3.2.6-123-g0e63fb8
You must: brew install git
Homebrew/homebrew-core (no Git repository)

[ @ ~]$ brew doctor
