gitlab本地分支push代码出错问题

最近业务上，本地分支的代码版本落后于远程分支，导致push失败，
comman line

# git config --global pull.rebase true
# 再次push到自己的开发分支，依然报错
# 提示先pull

# error: You have not concluded your merge (MERGE_HEAD exists).
# hint: Please, commit your changes before merging.
# fatal: Exiting because of unfinished merge.

# git commit -m 'up'
# git push origin 分支
# 成功！

根据提示解决问题，看报错
