Homebrew的安装

简介

Homebrew官网：http://brew.sh/index_zh-cn.html

Homebrew是Mac OSX上的软件包管理工具，能在Mac中方便的安装软件或者卸载软件，相当于linux下的apt-get、yum神器；Homebre可以在Mac上安装一些OS X没有的UNIX工具，Homebrew将这些工具统统安装到了 /usr/local/Cellar 目录中，并在 /usr/local/bin 中创建符号链接。

Homebrew的安装很简单，只需在终端下输入如下指令：

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

Homebrew能干什么？

又提示缺少套件啦？别担心，Homebrew 随时守候。

$ brew install wget

Homebrew 会将套件安装到独立目录，并将文件软链接至/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 的所有文件均会被安装到预定义目录下，所以您无需担心 Homebrew 的安装位置。

轻松创建您的 Homebrew 程式。

  $ brew create https://foo.com/bar-1.0.tgzCreated /usr/local/Library/Formula/bar.rb

以 git、 ruby 为其筋骨，所以借助您的相关知识，自由修改，并且可以简单撤回您的调改或者合并上游更新。

  $ brew edit wget # 使用 $EDITOR 编辑!

Homebrew 的程式都是简单的 Ruby 脚本：

  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
来安装 gems、用brew
来搞定那些依赖包。
