Homebrew介绍
Homebrew主要用于解决软件依赖包的关系。如其他linux系统Red hat有yum，Ubuntu有apt-get。可以说Homebrew就是mac下的apt-get、yum。
Homebrew安装
1.在终端中输入以下代码：
curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1
2.安装完毕后，执行命令查看是否安装成功。执行命令：brew
Please run brew update!
3.根据执行brew提示，要求我们执行brew update。那我们就执行
brew update
执行命令会出现这样的错误信息：
Error: /usr/local must be writable!
问题的原因是由于/user/local目录没有权限。这里我们给该目录进行授权。
如：sudo chown -R CalvinMackBook /usr/local```
4.执行：brew update

Homebrew no longer needs to have ownership of /usr/local. If you wish you can
return /usr/local to its default ownership with:
sudo chown root:wheel /usr/local
从安装信息我们可以看到,需要我们删除/usr/local/share/doc/homebrew目录，然后再执行安装。

Error: Could not link:

brew update
