这里有一个本地测试用例，可以在本地测试而不干扰远程设备：

~/p $ mkdir gittest    
~/p/git $ cd gittest/
~/p/gittest $ git init
Initialized empty Git repository in /Users/local_user/p/gittest/.git/
 ~/p/gittest $ touch testfile.txt
 ~/p/gittest $ git add testfile.txt
 ~/p/gittest $ git commit -m "initial commit"
[master (root-commit) 912ce0e] initial commit

 ~/p/gittest $ git tag

这里已经有很多很好的答案，但如果您需要删除所有标记，可以使用以下使用PowerShell的命令行：

foreach（$tag in（git tag））｛git tag-d$tag.Trim（）；git push origin:refs/tags/$tag｝

在这里，我们得到所有标签的列表，删除每个本地标签，然后删除远程标签（在GitHub上测试）。

更直接的方法是

git push --delete origin YOUR_TAG_NAME

在这种情况下，IMO前缀冒号语法有点奇怪

删除本地标记“12345”

git tag -d 12345

删除远程标记“12345”（例如，GitHub版本也是）

git push origin :refs/tags/12345

替代方法

git push --delete origin tagName
git tag -d tagName

我只是想分享我创建的别名，它做了同样的事情：

将以下内容添加到~/.gitconfig中

[alias]
    delete-tag = "!f() { \
            echo 'deleting tag' $1 'from remote/origin ausing command: git push --delete origin tagName;'; \
            git push --delete origin $1; \
            echo 'deleting tag' $1 'from local using command: git tag -d tagName;'; \
            git tag -d $1; \
        }; f"

用法如下：

-->git delete-tag v1.0-DeleteMe
deleting tag v1.0-DeleteMe from remote/origin ausing command: git push --delete origin tagName;
To https://github.com/jsticha/pafs
 - [deleted]             v1.0-DeleteMe
deleting tag v1.0-DeleteMe from local using command: git tag -d tagName;
Deleted tag 'v1.0-DeleteMe' (was 300d3ef22)

请注意，如果您有一个名为远程标记的远程分支，那么这些命令是不明确的：

git push origin :tagname
git push --delete origin tagname

因此，必须使用此命令删除标记：

git push origin :refs/tags/<tag>

这一个删除分支：

git push origin :refs/heads/<branch>

如果没有，则会出现如下错误：

error: dst refspec <tagname> matches more than one.
error: failed to push some refs to '<repo>'
