我有一个来自开发的分支
这是怎么回事
To git@gitlab.com:----/--------.git
! [rejected] mybranch -> mybranch (non-fast-forward)
error: failed to push some refs to 'git@gitlab.com:----/---------.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.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.```
