Mac 安装git

1. 打开Mac终端输入git命令
   如果出现以下代码说明已经安装

   usage: git [--version] [--help] [-C <path>] [-c <name>=<value>]
              [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
              [-p | --paginate | -P | --no-pager] [--no-replace-objects] [--bare]
              [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
              <command> [<args>]

   ‘git help -a‘ and ‘git help -g‘ list available subcommands and some
   concept guides. See ‘git help <command>‘ or ‘git help <concept>‘

2. 通过homebrew安装git

   1. 未安装homebrew选装homebrew
      /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

   2. 但是一般情况下报错
      curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused

   3. 解决办法：使用国内的镜像(我自己是选择中科技大学)

      /bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

   4. 然后提示安装命令行点击安装等待就好

3. 安装完之后咱们开始一些git的配置

   1. 设置username和email（github每次commit都会记录他们）

      git config --global user.name "wuliqqq"
      git config --global user.email "wuliqqq@outlook.com"
      

   2. 通过终端命令创建ssh key
      ssh-keygen -t rsa -C "wuliqqq@outlook.com"一直回车直至生成key

   3. 终端查看.ssh/id_rsa.pub文件
      cat .ssh/id_rsa.pub

   4. 登录你的github或者gitee（我自己登录的是gitee）gitee设置ssh key：进入设置界面，点击ssh公钥将你查看的.ssh/id_rsa.pub文件的内容复制进来
      

   5. 可以下载gitee上的项目啦
      git clone https:*//github.com/AlistarChen/LearnGit.git*
