mac install brew过程&问题解决

1. mac install brew过程

过程请参考 : 

https://blog.csdn.net/tterminator/article/details/47404877

简单说 , 就是一行命令搞定 :

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

( homebrew官方有可能更新了安装脚本，所以在安装brew时 , 上述安装脚本推荐从官方copy，官方网站如下：http://brew.sh/index_zh-cn.html。)

2. 遇到问题总结

error: could not lock config file /usr/local/Homebrew/.git/config: Permission denied

fatal: could not set 'core.repositoryformatversion' to '0'

Failed during: git init -q

3. 解决结果

从错误信息看，是获取homebrew版本库时遇到Permission denied。

查阅 https://raw.githubusercontent.com/Homebrew/install/master/install 可知，脚本尝试将版本库获取到`/usr/local`下。此时遇到Permission denied错误。

因此需要确保对`/usr/local`的完全访问权限，请尝试通过`sudo chown -R $(whoami) /usr/local`修改权限。
