mac下安装和使用brew 就像在linux下安装软件

一，安装brew

1，安装brew

curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1

2，安装完成后执行

brew

提示：Please run brew update!

3，按照提示更新，执行

brew update

报错：Error: /usr/local must be writable!

4，赋给/usr/local目录权限，执行sudo chown -R $(whoami) /usr/local，即

sudo chown -R fxp /usr/local

其中fxp为系统当前用户名。

5，再次执行
brew update
提示：

6，按照提示删除/usr/local/share/doc/homebrew，执行

rm -r -f /usr/local/share/doc/homebrew

7，再次执行

brew update

安装更新成功！

二，使用brew

命令行下执行brew，用法提示如下：

Example usage:  brew search [TEXT|/REGEX/]  brew (info|home|options) [FORMULA...]  brew install FORMULA...  brew update  brew upgrade [FORMULA...]  brew uninstall FORMULA...  brew list [FORMULA...]Troubleshooting:  brew config  brew doctor  brew install -vd FORMULADevelopers:  brew create [URL [--no-fetch]]  brew edit [FORMULA...]  https://github.com/Homebrew/brew/blob/master/docs/Formula-Cookbook.mdFurther help:  man brew  brew help [COMMAND]  brew home

常用命令有安装和卸载等，以安装和卸载autojump为例：
安装：sudo brew install autojump
卸载：sudo brew uninstall wget

查看安装软件的话，命令如下：

sudo brew search /apache*/

注意/apache*/是使用的正则表达式，用/分割。
