Git push 错误 Updates were rejected because the tip of your current branch is behind

Updates were rejected because the tip of your current branch is behind
更新被拒绝，因为你当前分支的尖端在后面。

Git冲突，解决方案：

1.使用强制push的方法：

$ git push -u origin master -f

这样会使远程修改丢失，一般是不可取的，尤其是多人协作开发的时候。

2.push前先将远程release修改pull下来

$ git pull origin master

$ git push -u origin master

3.若不想merge远程和本地修改，可以先创建新的分支：

$ git branch [name]

然后push

$ git push -u origin [name]
