Updates were rejected because the tip of your current branch is behind its remote counterpart.

写在前面的：在develop分支上创建了zxy分支来开发

问题描述：在zxy开发完了后 准备执行git push origin zxy ,执行完后提示

To http://git.xxxxx.com/static.git
 ! [rejected]        Zxy -> Zxy (non-fast-forward)
error: failed to push some refs to 'http://git.xxxxx.com/static.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

(x掉了一些东西)

看到上述提示 ，自己先执行了 git pull 但是提示

Already up-to-date.

蒙蔽了…..

解决办法：

重新在develop分支上创建一个别的分支开发。。。
