簡介
Homebrew官網：http://brew.sh/index_zh-cn.html
Homebrew是Mac OSX上的軟件包管理工具，能在Mac中方便的安裝軟件或者卸載軟件，相當于linux下的apt-get、yum神器；Homebre可以在Mac上安裝一些OS X沒有的UNIX工具，Homebrew將這些工具統統安裝到了 /usr/local/Cellar 目錄中，并在 /usr/local/bin 中創建符號鏈接。

腳本會解釋它的作用，然后在您的確認下執行安裝。高級安裝選項請看 這里（需要10.5）。
Homebrew能干什么？
又提示缺少套件啦？別擔心，Homebrew 隨時守候。
$ brew install wget
Homebrew 會將套件安裝到獨立目錄，并將文件軟鏈接至/usr/local。
$ cd /usr/local$ find CellarCellar/wget/1.16.1Cellar/wget/1.16.1/bin/wgetCellar/wget/1.16.1/share/man/man1/wget.1$ ls -l binbin/wget -> ../Cellar/wget/1.16.1/bin/wget
Homebrew 的所有文件均會被安裝到預定義目錄下，所以您無需擔心 Homebrew 的安裝位置。
輕松創建您的 Homebrew 程式。
$ brew create https://foo.com/bar-1.0.tgzCreated /usr/local/Library/Formula/bar.rb
以 git、 ruby 為其筋骨，所以借助您的相關知識，自由修改，并且可以簡單撤回您的調改或者合并上游更新。
$ brew edit wget # 使用 $EDITOR 編輯!
Homebrew 的程式都是簡單的 Ruby 腳本：
class Wget < Formula homepage "https://www.gnu.org/software/wget/" url "https://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz" sha256 "52126be8cf1bddd7536886e74c053ad7d0ed2aa89b4b630f76785bac21695fcd" def install system "./configure", "--prefix=#{prefix}" system "make", "install" endend
Homebrew 使 OS X 更完美。使用 gem
來安裝 gems、用brew
來搞定那些依賴包。
