Homebrew是神马
Linux系统有个让人蛋疼的通病，软件包依赖，好在当前主流的两大发行版本都自带了解决方案，Red hat有yum，Ubuntu有apt-get
神马，你用mac os，不好意Mac os木有类似的东东，泪奔中几经折腾总算找到了第三方支持：Homebrew，Homebrew简称brew，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，可以说Homebrew就是mac下的apt-get、yum神器
Homebrew安装
Homebrew的安装非常简单，打开终端复制、粘贴以下命令，回车，搞定(请放心使用，原汁原味的官方安装方法搬运）
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Homebrew使用
Homebrew使用没啥好说的了，常用的
搜索软件：brew search 软件名，如brew search wget
安装软件：brew install 软件名，如brew install wget

卸载homebrew方法：
1.打开终端，使用下面的卸载脚本： ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
2. 检查以下目录，是否存在原先安装，但是现在不需要的软件包
/usr/local
/usr/local/bin
/usr/local/include
/usr/local/lib
/usr/local/sbin
/usr/local/share
3. 修复步骤2中目录的权限：
sudo chown root:wheel <directory> ; sudo chmod 755 <directory>
