GIT中的强制PUSH

错误提示：
error: failed to push some refs to 'https://github.com/bnq456/bnq456.github.io.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.

有如下几种解决方法：
1.使用强制push的方法：
$ git push -u origin master -f

2.push前先将远程repository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]
