问题：
$ git push
To gitee.com:kekemuyu/xtpole.git
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'git@gitee.com:kekemuyu/xtpole.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.
解决：
git pull –rebase origin master
git push
