brew doctor警告:如何在PATH中添加git？

Question

我在OS X El Capitan上安装了Homebrew.在安装的最后几步中我应该安装git

brew install git

这很好.现在,如果我运行'brew doctor',就会发生这种情况:

$ 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

如果我再次运行'brew install git',我得到:

$ brew install git 
Warning: git-2.7.4 already installed

所以不用说我的git版本是2.7.4.'brew update'抛出:

$ brew update
Warning: git-2.7.4 already installed
Error: Git must be installed and in your PATH!

问题:如何修复PATH,以便在我的PATH中找到git,并且'brew doctor'结果为'您的系统已准备好酿造'？

附加信息:

• 哪个-git导致:

  $ which -a git
  /usr/local/bin/git
  /usr/local/bin/git
  /usr/bin/git
  

• 我尝试了很多潜在的修复,同时我执行了:

  echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile
  

  我的〜/ .bash_profile现在看起来像这样:

  # Setting PATH for Python 2.7
  # The orginal version is saved in .bash_profile.pysave
  PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
  export PATH=/usr/local/bin:$PATH
  

• 当我尝试安装cask时:

  $ brew tap caskroom/cask
  ==> Installing git
  Warning: git-2.7.4 already installed
  Error: Git is unavailable
  

• brew配置:

  $ brew config
  HOMEBREW_VERSION: 0.9.5
  ORIGIN: (none)
  HEAD: (none)
  Last commit: never
  HOMEBREW_PREFIX: /usr/local
  HOMEBREW_REPOSITORY: /usr/local
  HOMEBREW_CELLAR: /usr/local/Cellar
  HOMEBREW_BOTTLE_DOMAIN: https://homebrew.bintray.com

  OS X: 10.11.4-x86_64
  Xcode: 7.3
  CLT: 7.3.0.0.1.1457485338
  Clang: 7.3 build 703
  X11: N/A
  System Ruby: 2.0.0-p648
  Perl: /usr/bin/perl
  Python: /usr/local/bin/python => /usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/bin/python2.7
  Ruby: /usr/bin/ruby => /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby
  Java: 1.8.0_40
  

编辑:添加了其他信息.

EDIT2:添加了brew配置并添加了brew doctor前缀

Answer 1

这解决了我的问题:

cd /usr/local/Library/Homebrew
git pull origin master

之后我又跑了

brew update && brew upgrade

Answer 2

对我来说,这是由于缺少xcode工具引起的xcode-select --install.

其他几个建议的修复包括git fetch在brew目录和/或更改git core.autocrlf没有解决这个问题.

更详细地说,我从brew中卸载了git brew uninstall --force git,但Apple自己的git然后没有工作(/usr/bin/git --version报道missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun).

运行brew doctor建议运行xcode-select --install,我运行它,它修复了Apple的git,并且还修复了brew.(然后可以通过brew重新安装git brew install git.)
