一、 切换到被copy的分支(master),并且从远端拉取最新版本 $git checkout master $git pull 二、从当前分支拉copy开发分支 $git checkout -b dev Switched to a new branch 'dev' 三、 把新建的分支push到远端 $git push origin dev 四、拉取远端分支 $git pull There is no tracking information for the current branch. Please specify which branch you want to merge with. See git-pull(1) for details. git pull <remote> <branch> If you wish to set tracking information for this branch you can do so with: git branch --set-upstream-to=origin/<branch> dev 经过验证,当前的分支并没有和本地分支关联,根据提示进行下一步: 五、关联 $git branch --set-upstream-to=origin/dev 1 六、 再次拉取 验证 $git pull
