一、 切換到被copy的分支(master),並且從遠端拉取最新版本 $git checkout master $git pull 二、從當前分支拉copy開發分支 $git checkout -b dev Switched to a new branch 'dev' 三、 把新建的分支push到遠端 $git push origin dev 四、拉取遠端分支 $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 經過驗證,當前的分支並沒有和本地分支關聯,根據提示進行下一步: 五、關聯 $git branch --set-upstream-to=origin/dev 1 六、 再次拉取 驗證 $git pull
