Remove a deleted folder form git history
提问by Marten Bauer
How can I remove a folder that is already deleted from the git history?
如何删除已从 git 历史记录中删除的文件夹？
In my git repository I have a folder called /foo(1.2GB of size). I have deleted the folder foowith rm -rf /foobeause I do not need it any more. After many other commits I thought. Why is my remote repo so big...I have forgotten to do git rm --cached ...instead of rm -rf .... How can I now remove the folder from git history?
在我的 git 存储库中，我有一个名为/foo（1.2GB 大小）的文件夹。我已经删除了文件夹foo，rm -rf /foo因为我不再需要它了。在我想过许多其他提交之后。为什么我的远程仓库这么大...我忘了做git rm --cached ...而不是rm -rf .... 我现在如何从 git 历史记录中删除该文件夹？
git rm --cached /foowon't work because the folder is already delete in an earlier commit.
git rm --cached /foo将无法工作，因为该文件夹已在较早的提交中被删除。

The documentationcovers the similar case of purging a file from history:
该文档涵盖了从历史记录中清除文件的类似情况：
git filter-branch --index-filter 'git rm --cached --ignore-unmatch filename' HEAD
Since you are deleting a whole directory, add the -rflag to git rm:
由于您要删除整个目录，请将-r标志添加到git rm：
git filter-branch --index-filter \
'git rm -r --cached --ignore-unmatch path/to/directory' HEAD
Note that this operation will take several minutes on larger repositories.
请注意，在较大的存储库上，此操作将需要几分钟时间。
More importantly, it will make a new repository with distinct history and checksums. If you previously published your repository, the history of the new one will not be compatible with the history others have pulled.
更重要的是，它将创建一个具有不同历史记录和校验和的新存储库。如果您之前发布了您的存储库，则新存储库的历史记录将与其他人提取的历史记录不兼容。
