brew 给 MAC 插上 yum 的翅膀

什么是 brew？

如果你在羡慕 yum、apt-get 给 Linux 系统带来的便捷，不妨装上 brew 。还不明白它是做什么的？brew 全称为 Homebrew，官网（ http://brew.sh/ ）给它的定位是这样的：

The missing package manager for OS X. Homebrew installs the stuff you need that Apple didn’t.

brew 可以自动解决软件包的依赖关系，方便软件包的安装、更新和卸载。可以称得上是 MAC 系统中的一大神器！

安装

brew 的安装需要用到 ruby，MAC 中已经集成进去了。打开终端，执行命令：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

用法

帮助中说的已经比较清楚了：

➜  ~ brew -h
Example usage:
  brew (info|home|options) [FORMULA...]
  brew install FORMULA...
  brew uninstall FORMULA...
  brew search [TEXT|/PATTERN/]
  brew list [FORMULA...]
  brew update
  brew upgrade [FORMULA...]
  brew (pin|unpin) [FORMULA...]

Troubleshooting:
  brew doctor
  brew install -vd FORMULA
  brew (--env|config)

Brewing:
  brew create [URL [--no-fetch]]
  brew edit [FORMULA...]

以 p7zip 的安装为例：
