报错信息如下：
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://gitee.com/XXXX/XXXX.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.备注：提交之前 如果远程仓库和本地仓库不一致 记得先 git pull 否则回报上面的错误 git pull = git fetch + git merge
解决方法：
git pull --rebase origin master
