Git - 将远程仓库里的指定分支代码拉取到本地（本地不存在的分支）

本文转自：https://blog.csdn.net/qq_42764468/article/details/126406190

 

背景：在远程仓库创建了一个分支feature-haha，本地不存在这个分支

当我想从远程仓库里拉取一条本地不存在的分支时，下面命令将会自动创建一个新的本地分支，并与指定的远程分支关联起来：

git checkout -b 本地分支名 origin/远程分支名

① 远程仓库里有个分支 feature-haha，我本地没有该分支，我要把 feature-haha 代码拉到我本地,执行：

git checkout -b feature-haha origin/feature-haha

若成功，将会在本地创建新分支 feature-haha，并自动切到 feature-haha 上。

若失败，将会出现以下提示：

User@6-cpgh0012 MINGW64 /d/mycode/company_frame/company_member (feature-hh)
$ git checkout -b feature-haha origin/feature-haha
fatal: 'origin/feature-haha' is not a commit and a branch 'feature-haha' cannot be created from it

② 此时表示拉取不成功，需要先执行：git fetch

User@6-cpgh0012 MINGW64 /d/mycode/company_frame/company_member (feature-hh)
$ git fetch
From https://gitee.com/chahuaxiaozhan/company_member
 * [new branch]      feature-haha -> origin/feature-haha
 * [new branch]      feature-hh   -> origin/feature-hh

③ 再执行：git checkout -b feature-haha origin/feature-haha

User@6-cpgh0012 MINGW64 /d/mycode/company_frame/company_member (feature-hh)
$ git checkout -b feature-haha origin/feature-haha
Switched to a new branch 'feature-haha'
Branch 'feature-haha' set up to track remote branch 'feature-haha' from 'origin'.

User@6-cpgh0012 MINGW64 /d/mycode/company_frame/company_member (feature-haha)
$ git pull
Already up to date.

真实场景：

远程有一个分支：dev-offline-upgrade-v1，现在想基于 dev-offline-upgrade-v1 开发

$ git fetch
$ git checkout -b dev-offline-upgrade-v1 origin/dev-offline-upgrade-v1
$ git checkout feature-upgrade-ghh
$ git push origin feature-upgrade-ghh
