Git提交代码及异常处理方法

1.开始步骤

• 第一步：首先在gitee.com上创建一个项目，与你本地项目同名
• 第二步：在git bash 下操作

① git init 初始化本地仓库

② git add . 将当前文件加入到仓库

③ git commit -m 'first commit' 第一次提交项目文件

④ git remote add origin https://gitee.com/null_948_8938/ayiol_auth.git 关联远程仓库，蓝色为git项目URL

⑤ git push -u origin master 推送远程仓库

2.异常

• error: failed to push some refs to 'https://gitee.com/null_948_8938/ayiol_auth.git'
  
  hint: Updates were rejected because the remote contains work that you do
  
  hint: not have locally. This is usually caused by another repository pushing
  
  hint: to the same ref. You may want to first integrate the remote changes
  
  hint: (e.g., 'git pull ...') before pushing again.
  
  hint: See the 'Note about fast-forwards' in 'git push --help' for details.
  
  
  

  方法：报错因为远程仓库与本地仓库文件不一致，使用git pull拉下远程代码到本地

  git pull
  

• warning: no common commits
  
  remote: Counting objects: 3, done.
  
  remote: Compressing objects: 100% (2/2), done.
  
  remote: Total 3 (delta 0), reused 0 (delta 0)
  
  Unpacking objects: 100% (3/3), done.

  * [new branch] master -> origin/master
  
  There is no tracking information for the current branch.
  
  Please specify which branch you want to merge with.
  
  See git-pull(1) for details.
  
  git pull <remote> <branch>
  
  If you wish to set tracking information for this branch you can do so with:
  
  git branch --set-upstream-to=origin/<branch> master
  
  

  原因：报错原因是没有指定本地master和远程origin/master的连接，

  执行git branch --set-upstream master origin/master，设置链接

  git branch --set-upstream master origin/master
  

• fatal: the '--set-upstream' option is no longer supported. Please use '--track' or '--set-upstream-to' instead.
  
  

  原因：

  再次执行：git pull origin master
  
  

• fatal: refusing to merge unrelated histories 拒绝合并不相关的历史
  

  原因：

  报错原因是本地仓库与远程仓库不同
  
  解决方案：
  
  git添加一句代码，这句代码是在git2.9.2版本发生的，最新版本需要添加 --allow-unrelated-histories，此代码为忽略不相关历史文件
  
  即：git pull origin master --allow-unrelated-histories
   
  重新git push origin master ，不在报错，推送完成
