Brew无法找到git，即使git in path（Mac / OSX）

Question

Installing brew reports that it cannot find git, and dies with an error. Brew appears to have be installed (successfully?)

> brew

(prints the usual help)

...but brew doctor is not happy:

This is what I get when I run brew doctor, (and when I installed brew for the first time as instructed on the Homebrew homepage.)

> brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: Git could not be found in your PATH.
Homebrew uses Git for several internal functions, and some formulae use Git
checkouts instead of stable tarballs. You may want to install Git:
  brew install git
Error: Git is unavailable
Error: Failure while executing: /usr/local/bin/brew tap homebrew/core -q

My PATH:

> echo $PATH
/usr/local/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Git is here:

> which git
/usr/bin/git

Answer 1

你安装了命令行工具吗？

xcode-select --install

Answer 2

Brew probably works properly for you and you can brew install without any issues.

Looks like brew doctor would prefer that you install git with brew instead of using the OSX system default installation of git .

To make brew doctor happy, run:

> brew install git

That will install git to /usr/local/bin/git and likely make the error go away.
