$ git push origin master To gitee.com:lpiueng/pic-go.git ! [rejected] master -> master (non-fast-forward) error: failed to push some refs to 'gitee.com:lpiueng/pic-go.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.

这个错误提示是因为你当前的分支不是最新的，需要先将远程仓库的最新代码拉取到本地仓库，然后再进行推送。你可以使用以下命令：

git pull origin master

这会将远程仓库的最新代码合并到本地仓库的当前分支上。然后再执行推送命令：

git push origin master

这次推送应该就可以成功了。
