I have been struggling with this for a few hours. I am on a Mac using Yosemite. I had homebrew installed, and was using git just fine. I tried doing $git add -iand I got this error:
我已经为此苦苦挣扎了几个小时。我在使用 Yosemite 的 Mac 上。我安装了自制软件，并且使用 git 就好了。我尝试这样做$git add -i，但出现此错误：

所以我按照这里的说明操作： Can't locate Git.pm in @INC
$brew uninstall gitworked fine, but after I tried to $brew install gitI've been stuck in a terrible cycle.
$brew uninstall git工作正常，但在我尝试之后，$brew install git我陷入了一个可怕的循环。
% brew install git
Error: git-git already installed
To install this version, first `brew unlink git'
% brew unlink git
Error: No such keg: /usr/local/Cellar/git
% brew link git
Error: No such keg: /usr/local/Cellar/git
% git --version
git version 1.9.3 (Apple Git-50)
% brew upgrade git
==> Upgrading 1 outdated package, with result:
git 2.2.2
Error: /usr/local/Library/LinkedKegs/git is not a valid keg
% brew install git
Error: git-git already installed
To install this version, first `brew unlink git'

I just want to get homebrew & git back to normal and linked to the correct repo again. I'm really rough around the edges at this stuff, so any help would be greatly appreciated!
我只想让自制软件和 git 恢复正常并再次链接到正确的存储库。我在这方面真的很粗糙，所以任何帮助将不胜感激！

Give another go at force removing the brewed version of git
再次强行删除 git 的酿造版本
brew uninstall --force git
Then cleanup any older versions and clear the brew cache
然后清理所有旧版本并清除 brew 缓存
brew cleanup --force -s git
Remove any dead symlinks
删除任何无效的符号链接
brew cleanup --prune-prefix
Then try reinstalling git
然后尝试重新安装git
brew install git
If that doesn't work, I'd remove that installation of Homebrew altogether and reinstall it. If you haven't placed anything else in your brew --prefixdirectory (/usr/localby default), you can simply rm -rf $(brew --prefix). Otherwise the Homebrew wiki recommends using a script at https://gist.github.com/mxcl/1173223#file-uninstall_homebrew-sh
如果这不起作用，我会完全删除 Homebrew 的安装并重新安装它。如果你没有在你的brew --prefix目录中放置任何其他东西（/usr/local默认情况下），你可以简单地rm -rf $(brew --prefix). 否则 Homebrew wiki 建议使用https://gist.github.com/mxcl/1173223#file-uninstall_homebrew-sh 上的脚本

Had a similar issue while installing "Lua" in OS X using homebrew. I guess it could be useful for other users facing similar issue in homebrew.
使用自制软件在 OS X 中安装“Lua”时遇到了类似的问题。我想这对于在自制软件中面临类似问题的其他用户可能很有用。
On running the command:
在运行命令时：
$ brew install lua
$ brew install lua
The command returned an error:
命令返回错误：
Error: /usr/local/opt/lua is not a valid keg
(in general the error can be of /usr/local/opt/ is not a valid keg
错误: /usr/local/opt/lua is not a valid keg
(通常错误可能是 /usr/local/opt/ is not a valid keg
FIXED it by deleting the file/directory it is referring to, i.e., deleting the "/usr/local/opt/lua" file.
通过删除它所指的文件/目录来修复它，即删除“/usr/local/opt/lua”文件。
root-user # rm -rf /usr/local/opt/lua
根用户 # rm -rf /usr/local/opt/lua
And then running the brew install command returned success.
然后运行 brew install 命令返回成功。
