How to clear git caches?
提问by Carmine
When I list my branches with git branch -a, git shows me remote branches I can't actually find on my remote(gitlab). I tried to checkout and track those branches, and to my big surprise, git did it. But when I do for example git push origin :branch_name, git says that the remote ref does not exist, thus proving that I do not have those branches in my remote. Hence I have a question, are those branches stored in some kind a local cache? And if yes, how to clear it?
当我用 列出我的分支时git branch -a，git 会显示我在我的远程（gitlab）上实际上找不到的远程分支。我试图检查和跟踪这些分支，令我惊讶的是，git 做到了。但是，例如git push origin :branch_name，当我这样做时，git 说远程引用不存在，从而证明我的远程中没有这些分支。因此我有一个问题，这些分支是否存储在某种本地缓存中？如果是，如何清除它？

Use git fetch -pto prune your local caches
使用git fetch -p修剪你的本地缓存

Like mentioned on cleaning up old remote git branches, you should use git remote prune origin.
就像在清理旧的远程 git 分支时提到的那样，您应该使用git remote prune origin.
I didn't use the other two commands mentioned there.
我没有使用那里提到的其他两个命令。
