brew doctor 警告：如何将 git 添加到 PATH？

brew doctor Warning: How to add git to PATH?

提问by ncw

I installed Homebrew on OS X El Capitan. In the last steps of the installation I was supposed to install git with

我在 OS X El Capitan 上安装了 Homebrew。在安装的最后一步中，我应该安装 git

brew install git

which was fine. Now if I run 'brew doctor' this happens:

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

If I run 'brew install git' again, I get:

如果我再次运行“brew install git”，我会得到：

$ brew install git 
Warning: git-2.7.4 already installed

So needless to say my git version is 2.7.4. 'brew update' throws:

所以不用说我的 git 版本是 2.7.4。“酿造更新”抛出：

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

Question:How do I fix my PATH so git can be found in my PATH and 'brew doctor' results in 'Your system is ready to brew'?

问题：如何修复我的 PATH 以便可以在我的 PATH 中找到 git 并且“brew doctor”结果为“您的系统已准备好进行 brew”？

Additional Information:

附加信息：

• which -a git results in:

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

• I tried a lot of potential fixes, meanwhile I executed:

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

  My ~/.bash_profile now looks like this:

  # 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
  

• When I try to install cask:

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

• brew config:

  $ brew config
  HOMEBREW_VERSION: 0.9.5
  ORIGIN: (none)
  HEAD: (none)
  Last commit: never
  HOMEBREW_PREFIX: /usr/local
  HOMEBREW_REPOSITORY: /usr/local

• which -a git 结果：

  $ 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
  

• 当我尝试安装桶时：

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

• 酿造配置：

  $ brew config

  HEAD: (none)
  Last commit: never
  HOMEBREW_PREFIX: /usr/local

this fixed my problem:

这解决了我的问题：

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

after that I ran again

之后我又跑了

brew update && brew upgrade

For me this was caused by missing xcode tools, fixed by xcode-select --install.

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

Several other suggested fixes including git fetchin the brew directory and/or changing git core.autocrlfdid not fix this.

包括git fetchbrew 目录和/或更改 git在内的其他几个建议的修复程序core.autocrlf没有解决这个问题。

In more detail I uninstalled git from brew brew uninstall --force git, but Apple's own git then didn't work (/usr/bin/git --versionreported missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun).

更详细地说，我从 brew 卸载了 git brew uninstall --force git，但是 Apple 自己的 git 没有工作（/usr/bin/git --version报告missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun）。

Running brew doctorsuggested running xcode-select --install, I ran this and it fixed Apple's git, and also fixed brew. (Possible to then reinstall git via brew brew install git.)

Runningbrew doctor建议 running xcode-select --install，我运行了它，它修复了 Apple 的 git，还修复了 brew。（然后可以通过 brew 重新安装 git brew install git。）

Simply run:

只需运行：

export PATH=/usr/local/bin:$PATH

Your PATHvariable should look something like

你的PATH变量应该看起来像

PATH="/usr/bin:/usr/local/bin"

I found the solution to my problem. It was caused by a wrong fileformat of /usr/local/Library/ENV/scm/git:

我找到了解决我的问题的方法。这是由错误的文件格式引起的/usr/local/Library/ENV/scm/git：

$ /usr/local/Library/ENV/scm/git --version
-bash: /usr/local/Library/ENV/scm/git: /bin/sh^M: bad interpreter: No such file or directory

So I edited the fileformat:

所以我编辑了文件格式：

$ vi /usr/local/Library/ENV/scm/git

Press 'ESC', write :set fileformat=unix, Press 'Enter', write :wq!.

按“ESC”，写:set fileformat=unix，按“Enter”，写:wq!。

That fixed it for me.

那为我修好了。

I ran into the same symptom when tyring to run brew update.

我在跑步时遇到了同样的症状brew update。

In my case problem was caused by have a bash variable of GITset (to a directory). So the solution was to unset it for the brew command

在我的情况下，问题是由设置的 bash 变量GIT（到目录）引起的。所以解决方案是为 brew 命令取消设置

$ GIT= brew update

Likely problem with libintl.8.dylib as in many other similar issues:

与许多其他类似问题一样，libintl.8.dylib 可能存在问题：

locate libintl.8.dylib

if /gettext//libintl.*.dylib exists

如果/gettext//libintl.*.dylib 存在

brew link -f gettext

go to (depending on version)

转到（取决于版本）

cd /usr/local/Homebrew 
cd /usr/local/Library/Homebrew 

and execute (make sure you're in .../Homebrew directory)

并执行（确保你在 .../Homebrew 目录中）

git pull origin master
rm -fr ".git/rebase-apply"
brew update && brew upgrade

this last will took some time, but afterwards everything should work fine.

这最后需要一些时间，但之后一切都应该正常工作。

If you're like me: using macOS El Capitan and don't have /usr/local/Library/ENV/scm/git, here's what you can do.

如果您像我一样：使用 macOS El Capitan 而没有/usr/local/Library/ENV/scm/git，您可以执行以下操作。

cd /usr/local/
# The folder where you've installed Homebrew
git config --list --local

Look for: core.autoxrlf=false

寻找： core.autoxrlf=false

If don't see it run: git config --local core.autocrlf false

如果没有看到它运行： git config --local core.autocrlf false

Then run:

然后运行：

git fetch origin
git reset --hard origin/master
brew update
