git rebase遇到的一个疑问
最近工作git管理方面遇到一个疑问，如下:
我有两个分支dev 和 feature 分支，目前出现如下疑问，
我在feature分支先执行 git pull origin feature操作，更新本地的分支到最新，然后执行了git rebase dev操作，最后执行git push origin feature时会遇到如下错误
To ssh://xxx@git.xxxx.com/project_xx/xxx.git
! [rejected] feature -> feature (non-fast-forward)
error: failed to push some refs to 'ssh://xxx@git.xxxx.com/project_xx/xxx.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.
最后再执行一次git pull origin feature操作才能成功，这样会产生一条merge log，并且内容为空Showing 0 changed files。
疑问，为什么我之前已经执行了
pull更新到最新了？不知道是不是我操作流程的问题，请大牛们指教，谢谢！
