brew 安装时要按xcode问题
其实不需要的，分别运行以下三条命令就行了
git clone git://github.com/robbyrussell/oh-my-zsh.git ~/.oh-my-zsh
cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
最后一条可能不是最新，bash里面会有提示的，复制粘贴就行了
安装项wget-get一样的brew
我这新创建的 /usr/local
# 安装brew 请在普通用户下执行 #
$> ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
# 在这里演示一下安装wget #
brew install wget
# 也可能用brew安装一个NGINX #
brew install nginx
# 使用brew卸载NGINX #
brew uninstall nginx
# 修改nginx安装配置 #
brew edit nginx
# 搜索PHP安装包 #
brew searc /php/
# 更新源 #
brew update
# 查看旧的软件 #
brew outdated
# 更新软件 #
brew upgrade
# 更新软件包 #
brew upgrade wget
# 修复依赖 #
brew --prefix
# 强制卸载NGINX #
brew uninstall nginx --force
