如何在Python中删除带有.git文件夹的目录

我正在尝试创建一个程序来帮助备份。它的工作原理是将项目复制到备份位置。在复制之前，它会进行一些检查。我检查文件夹以前是否备份过，如果备份过，我需要在复制新备份之前删除该文件夹

当我备份没有.git文件夹的项目时，效果很好。一旦项目目录有一个.git文件夹，它就会中断。它不会删除.git文件夹，这会弄乱程序的其余部分。我似乎找不到删除.git文件夹的方法

我的代码：

我在谷歌上寻找答案已经有一段时间了。这个问题的答案不起作用

这是我想到的。试试看，希望它能奏效。它假定您在Windows上

注意：on_rm_error方法来自

非常感谢。我让它稍微工作了一下，它工作得很好。
