gitee上传失败问题

error: failed to push some refs to 'https://gitee.com/herryxm/hhgolbalk3.git' 
hint: Updates were rejected because the tip of your current branch is behind

hint: 'git pull ...') before pushing again. 
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

当执行git push orgin master时报如上错误，原因是远程仓库中有修改没有同步到本地仓库中。我的情况是远程仓库不为空，创建时新增了readme文件。，可以执行：

git pull --rebase origin master或 

git pull --allow-unrelated-histories

后在执行git push origin master,成功。
