git branch -d is to delete the branch

为情所困 · Answer

The error message is obvious. There is no such directory. Are you sure this branch exists?

给我你的怀抱 · Answer

Make sure you delete the corresponding branch. git branch查看分支是否存在，注意远程分支一定要有:

#删除远程分支
git push origin :dev
#删除本地分支
git branch -D dev

Not particularly understandable. . . Why do I need git checkout -b to delete a branch? If you want to delete a branch, shouldn't you first switch to another branch and then git branch -d?

迷茫 · Answer

-b means build, which means new.
-d means delete. This is the deletion you want.

git branch -D branch-name (branch name)
Force deletion
