我正在尝试在我的git存储库中重写我的历史记录，因为我需要删除包含受限信息的文件。
这就是：
$ git filter-branch --index-filter 'git rm --cached --ignore-unmatch FILE' master
Cannot rewrite branch(es) with a dirty working directory.
所以我认为“这很奇怪，我很确定我没有未提交的更改”，我跑了：
$ git status -u
# On branch master
nothing to commit (use -u to show untracked files)
这里发生了什么？有没有人知道会发生什么？这个存储库中有子模块。
我有18个子模块（所有Vim插件），这是他们的状态。认为这可能是有用的信息。
$ for i in $(ls); do cd $i; git status -u; cd ..; done;
# Not currently on any branch.
nothing to commit (working directory clean)
# Not currently on any branch.
nothing to commit (working directory clean)
# Not currently on any branch.
nothing to commit (working directory clean)
# Not currently on any branch.
nothing to commit (working directory clean)
# Not currently on any branch.
nothing to commit (working directory clean)
# Not currently on any branch.

答案 0 :(得分：7)
这主要是猜测，但错误可能是由git v1.7.7.1中的fixed错误引起的（该错误是在原始帖子之后发布的）。来自提交消息：
Filter-branch已经要求我们在开始之前有一个干净的工作树。但是，它在检查之前无法刷新索引，这意味着在严重肮脏的情况下它可能是错误的。
