用于在Windows上进行符号链接转换的Git挂钩

我扩展了Git的命令列表,如Git Symlinks in Windows

我读了关于钩子并创建了post-checkout钩子：

#!/bin/sh
exec git rm-symlinks

它可以工作,当我执行git checkout #branch_with_symlink时,但当我做下一次checkout时,git写道：

error: Your local changes to the following files would be overwritten by checkout:
#path_to_symlink
Please,commit your changes or stash them before you can switch branches.

git状态：

# On branch #branch_with_symlink
nothing to commit,working directory clean

git没有预先签出钩子,我不明白,我是如何进行这种转换的
