homebrew - 我无法使用 Homebrew 安装 zsh

Question

OS X El Capitan 版本 10.11.2

我尝试过 brew update ，但会显示此错误消息。

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- mach (LoadError)

我也尝试过 brew install zsh ，但会显示上述消息。

请让我知道如何修复此错误消息。

The problem mainly occurs after updating OS X to El Capitan (OS X 10.11). This is mainly because of file permission issues with file El Capitan’s new SIP process. Try changing permissions of /usr/local directory.

$ sudo chown -R $(whoami):admin /usr/local  

If it still doesn't work, use following steps and everything will be fine. This may be because homebrew is not updated.

1. open terminal  
2. $ cd /usr/local  
3. $ git reset --hard  
4. $ git clean -df
5. $ brew update
