Purging file from Git repo failed, unable to create new backup
提问by Cardin Lee JH
I tried to remove a file from my remote repo by running:
我试图通过运行从我的远程仓库中删除一个文件：
git filter-branch --index-filter 'git rm --cached --ignore-unmatch Rakefile' HEAD
But Git complains that
但是 Git 抱怨说
Cannot create new backup. A previous backup already exists in refs/original/
Force overwriting the backup with -f
rm: cannot remove /.git-rewrite/backup-refs : Permission denied
rm: cannot remove directory /.git-rewrite : Directory not empty
无法创建新备份。以前的备份已存在于 refs/original/
用 -f
rm强制覆盖备份：无法删除 /.git-rewrite/backup-refs：权限被拒绝
rm：无法删除目录 /.git-rewrite：目录不为空
This was after I already deleted the .git-rewrite directory on Windows.
这是在我已经删除了 Windows 上的 .git-rewrite 目录之后。
How can I remove that file? It's a 29Mb file sitting on my repo, so I quite need to remove the file.
我怎样才能删除那个文件？这是一个 29Mb 的文件，位于我的存储库中，因此我非常需要删除该文件。
I tried to delete the commit in git rebase -i, but apparently because the commit touched a lot of different files, Git complains of conflicts and I aborted to be safe.
我试图删除 中的提交git rebase -i，但显然因为提交涉及了很多不同的文件，Git 抱怨冲突，为了安全起见，我中止了。

You have already performed a filter-branch operation. After filter-branch, Git keeps refs to the old commits around, in case something goes wrong.
您已经执行了过滤器分支操作。在过滤分支之后，Git 保留对旧提交的引用，以防出现问题。
You can find those in .git/refs/original/…. Either delete that directory and all files within, or use the -fflag to force Git to delete the old references.
你可以在.git/refs/original/…. 删除该目录和其中的所有文件，或使用该-f标志强制 Git 删除旧引用。
git filter-branch -f \
--index-filter 'git rm --cached --ignore-unmatch Rakefile' HEAD

Use this command to remove original backup:
使用此命令删除原始备份：
git update-ref -d refs/original/refs/heads/master
Here is gist I used to filter-branch my git repo: https://gist.github.com/k06a/25a0214c98bc19fd6817
这是我用来过滤分支我的 git repo 的要点：https: //gist.github.com/k06a/25a0214c98bc19fd6817

I had the same problem and the answer above didn't fix it. There was no .git/refs/original/ directory left. The solution for me was to delete the .git/packed-refs file.
我遇到了同样的问题，上面的答案没有解决。没有 .git/refs/original/ 目录了。我的解决方案是删除 .git/packed-refs 文件。

Add a force to the filter branch command.
向过滤器分支命令添加强制。
