常说的先拉再推，先pull再push

遇到问题：

! [rejected] dev-fl -> dev-fl (non-fast-forward)

error: failed to push some refs to ‘....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.

解决：

git add 和 git commit 已经执行成功

git status （显示个人分支），下面依次执行下面三个

git pull origin master

git pull origin dev

git push origin dev-fl 

分支推送成功。
