Mac中安裝Git

Mac 安裝git

1. 打開Mac終端輸入git命令
   如果出現以下代碼說明已經安裝

   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>]
   
   These are common Git commands used in various situations:
   
   start a working area (see also: git help tutorial)
      clone     Clone a repository into a new directory
      init      Create an empty Git repository or reinitialize an existing one
   
   work on the current change (see also: git help everyday)
      add       Add file contents to the index
      mv        Move or rename a file, a directory, or a symlink
      restore   Restore working tree files
      rm        Remove files from the working tree and from the index
   
   examine the history and state (see also: git help revisions)
      bisect    Use binary search to find the commit that introduced a bug
      diff      Show changes between commits, commit and working tree, etc
      grep      Print lines matching a pattern
      log       Show commit logs
      show      Show various types of objects
      status    Show the working tree status
   
   grow, mark and tweak your common history
      branch    List, create, or delete branches
      commit    Record changes to the repository
      merge     Join two or more development histories together
      rebase    Reapply commits on top of another base tip
      reset     Reset current HEAD to the specified state
      switch    Switch branches
      tag       Create, list, delete or verify a tag object signed with GPG
   
   collaborate (see also: git help workflows)
      fetch     Download objects and refs from another repository
      pull      Fetch from and integrate with another repository or a local branch
      push      Update remote refs along with associated objects
   
   'git help -a' and 'git help -g' list available subcommands and some
   concept guides. See 'git help <command>' or 'git help <concept>'
   to read about a specific subcommand or concept.
   See 'git help git' for an overview of the system.
   

2. 通過homebrew安裝git

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

   2. 但是一般情況下報錯
      curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused

   3. 解決辦法：使用國內的鏡像(我自己是選擇中科技大學)

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

   4. 然后提示安裝命令行點擊安裝等待就好

3. 安裝完之后咱們開始一些git的配置

   1. 設置username和email（github每次commit都會記錄他們）

      git config --global user.name "wuliqqq"
      git config --global user.email "[e-mail]"
      

   2. 通過終端命令創建ssh key
      ssh-keygen -t rsa -C "[e-mail]"一直回車直至生成key

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

   4. 登錄你的github或者gitee（我自己登錄的是gitee）gitee設置ssh key：進入設置界面，點擊ssh公鑰將你查看的.ssh/id_rsa.pub文件的內容復制進來
      

   5. 可以下載gitee上的項目啦
      git clone https:*//github.com/AlistarChen/LearnGit.git*
