就这么简单。为了在本地和远程重命名一个Git分支，使用这个代码片段(经过测试，效果很好):

git branch -m <oldBranchName> <newBranchName>
git push origin :<oldBranchName>
git push --set-upstream origin <newBranchName>

解释:

重命名步骤:

Git参考: 使用-m或-m选项，<oldbranch>将被重命名为<newbranch>。如果 <oldbranch>有一个对应的reflog，它被重命名为匹配 <newbranch>，并且创建一个reflog条目来记住这个分支 重命名。如果<newbranch>存在，则必须使用-M强制重命名 发生。

删除步骤:

Git参考: 找到一个与experimental in匹配的ref 原始存储库(例如refs/heads/experimental)，并删除它。

远程存储库步骤的更新(用于跟踪的上游参考):

Git参考: 对于每个最新或成功推送的分支，添加upstream (tracking)引用，由less参数使用 Git-pull[1]等命令。有关更多信息，请参见 分支。<名称>。在git-config[1]中合并。

分支重命名现在可以通过GitHub API使用

你可以用GitHub REST API重命名一个分支。

你可以通过gh CLI轻松运行API命令，就像这样:

gh api "repos/{owner}/{repo}/branches/{branch}/rename" -f new_name={newBranch}

在GitHub端，您可以使用新的(2021年1月)“支持重命名现有分支”(受保护的分支只能由管理员重命名，见末尾)

跟随本教程:https://docs.github.com/en/github/administering-a-repository/renaming-a-branch

参见“如何在GitHub网站上重命名分支?”。

这是一个更好的方法，因为以这种方式重命名分支(在github.com上)将:

Re-target any open pull requests Update any draft releases based on the branch Move any branch protection rules that explicitly reference the old name Update the branch used to build GitHub Pages, if applicable Show a notice to repository contributors, maintainers, and admins on the repository homepage with instructions to update local copies of the repository Show a notice to contributors who git push to the old branch Redirect web requests for the old branch name to the new branch name Return a "Moved Permanently" response in API requests for the old branch name

2021年12月更新:

Restrict renaming protected branches to admins Now, only admins can rename branches that are protected by branch protection rules. GitHub allows repository collaborators to rename every branch in a repository, with the exception of the default branch. When a collaborator renames a branch, any non-wildcard branch protection rules that apply to that branch are also changed to match the branch's new name. Because only admins can modify branch protection rules, renaming of a protected branch is now limited to admin users. For more information, visit Renaming a branch and Managing a branch protection rule.

这是Hazarapet Tunanyan回答的附加条件。

git branch -m old_branch new_branch         # Rename branch locally


git push origin :old_branch                 # Delete the old branch
# You might be getting an error doing the above step, skip to the next step

git push --set-upstream origin new_branch   # Push the new branch, set local branch to track the new remote

你在git push origin:old_branch时会得到一个错误，因为你试图删除的old_branch可能是默认的分支。

只需要执行另外2步，然后转到github，从设置中更改默认分支，然后你就可以执行git push origin:old_branch了。

以下是对我有效的方法:

首先创建新分支: Git推送github newname:refs/heads/newname 在GitHub网站上，进入设置并将默认分支更改为newname 删除oldname Git推送github——删除旧名

下面的命令对我有用:

git push origin :old-name-of-branch-on-github
git branch -m old-name-of-branch-on-github new-name-for-branch-you-want
git push origin new-name-for-branch-you-want
