怎样删除 branch -a 存在而 branch 和 GitHub 上都不存在的分支?

Question

我在 git branch -a 看到的分支数量明显比 git branch 和网页上看到的多,
看名字应该是本地的开发的分支, 线上已经删除, 本地删除了, 但是 branch -a 里没有删除.
怎样删除这里边的分支呢?

Answer 1

git fetch origin --prune

or

git branch -d -r origin/branch_name

Answer 2

git branch -d localBranch

---

According to what the poster said in the comments, then
git fetch --all

Answer 3

git push origin :gh-pages
git branch -D gh-pages
git branch --bare gh-pages

It’s not what I say, help is there. I really don’t know how to delete it. I can just click branches in the web page.
