git 查看和删除分支

查看本地分支：

hs@DESKTOP-L2NPMSM MINGW64 /d/project/js/iot-mis-web/code/iot-mis-web (fix_view_task)
$ git branch
  dev
* fix_view_task
  master

查看所有分支：（本地和远程）

hs@DESKTOP-L2NPMSM MINGW64 /d/project/js/iot-mis-web/code/iot-mis-web (fix_view_task)
$ git branch -a
  dev
* fix_view_task
  master
  remotes/origin/dev
  remotes/origin/fix_view_task
  remotes/origin/master

操作过程:

在gitlab远程的dev分支的一个commit节点创建 fix_view_task 分支，本地同步下远程的变化，本地切换到 fix_view_task  分支进行开发，bug修改完后，本地切换到 dev 分支，将 fix_view_task 分支的修改合并到 dev 上，然后将 dev 推到远程，然后jenkins 从远程dev分支拉取进行构建。此时我认为 fix_view_task 分支已经没有用了，我需要对它进行删除操作。。。

删除本地 fix_view_task ：

hs@DESKTOP-L2NPMSM MINGW64 /d/project/js/iot-mis-web/code/iot-mis-web (fix_view_task)
$ git branch -d fix_view_task
error: Cannot delete branch 'fix_view_task' checked out at 'D:/project/js/iot-mis-web/code/iot-mis-web'

hs@DESKTOP-L2NPMSM MINGW64 /d/project/js/iot-mis-web/code/iot-mis-web (fix_view_task)
$ git checkout dev
Switched to branch 'dev'
Your branch is up to date with 'origin/dev'.

hs@DESKTOP-L2NPMSM MINGW64 /d/project/js/iot-mis-web/code/iot-mis-web (dev)
$ git branch -d fix_view_task
warning: deleting branch 'fix_view_task' that has been merged to
         'refs/remotes/origin/fix_view_task', but not yet merged to HEAD.
Deleted branch fix_view_task (was 5e79554).

删除远程 fix_view_task ：

hs@DESKTOP-L2NPMSM MINGW64 /d/project/js/iot-mis-web/code/iot-mis-web (dev)
$ git push origin :fix_view_task
To 172.16.79.20:front-end/iot-mis-web.git
 - [deleted]         fix_view_task

 可能遇到的问题：

比如： remote ref does not exist ，遇到这个问题的话是本地和远程之间的关联有问题了，我们在删除前先执行下 git fetch -p origin

git delete remotes: remote refs do not exist
