hint:

Check out this branch and integrate the remote changes (e.g. 'git pull ...') before pushing again.

============================

 强推： 

git push --force-with-lease origin 本地分支名:远端分支名
git push --force origin master:master

============================

 如果强制推送，则可能会给签出该分支的所有其他用户造成问题。风险较小的解决方案是从分离的头创建一个临时分支，然后将该分支合并到主分支中：

git branch temp-branch
git checkout master
git merge temp-branch
git push origin master
