Mac--Git安装
注意：在安装Git前，可先安装homebrew，应用brew命令安装Git即可。
一。Mac 安装homebrew
参考博客：https://blog.csdn.net/yuexiaxiaoxi27172319/article/details/51279369
Homebrew官网 http://brew.sh/index_zh-cn.html
说明：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
1。Homebrew安装
//打开终端，输入命令
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
2。Homebrew使用
//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
//卸载软件：
brew remove 软件名，如brew remove wget brew uninstall 软件名，如brew uninstall wget
3。Homebrew安装成功显示如下：

二。应用brew安装Git版本控制工具
参考博客：https://blog.csdn.net/xiaohanluo/article/details/53214933
1。打开终端，输入命令：brew install git
2。安装好Git后，配置用户名和用户邮箱，以后每次与Git的交互都会使用该信息
git config --global user.name "your_name"
git config --global user.email "your_email@gmail.com"
配置信息可以更改，以后想要更改使用上面指令就可以。同时可以使用git config --list指令查看Git的配置信息。
Git默认是大小写不敏感的，也就是说，将一个文件名某个字母做了大小写转换的修改Git是忽略这个改动的，导致在同步代码时候会出现错误，所以建议大小把Git设置成大小写敏感。
git config core.ignorecase false
