推荐答案

简单来说，定义如下环境变量:

In short, define the following environment variable:

CYGWIN=winsymlinks:nativestrict

根据Cygwin 文档:

如果设置为 winsymlinks:native 或 winsymlinks:nativestrict，Cygwin 会在文件系统和支持它们的操作系统版本上创建符号链接作为本地 Windows 符号链接.

If set to winsymlinks:native or winsymlinks:nativestrict, Cygwin creates symlinks as native Windows symlinks on filesystems and OS versions supporting them.

winsymlinks:native 和 winsymlinks:nativestrict 之间的区别是:如果文件系统支持本地符号链接并且 Cygwin 由于某种原因无法创建本地符号链接，它将回退到使用 winsymlinks:native 创建 Cygwin 默认符号链接，而使用 winsymlinks:nativestrict symlink(2) 系统调用将立即失败.

The difference between winsymlinks:native and winsymlinks:nativestrict is this: If the filesystem supports native symlinks and Cygwin fails to create a native symlink for some reason, it will fall back to creating Cygwin default symlinks with winsymlinks:native, while with winsymlinks:nativestrict the symlink(2) system call will immediately fail.

您还应该确保以提升的权限运行 Cygwin(右键单击快捷方式并选择以管理员身份运行，或设置 mintty 快捷方式属性，高级 → 以管理员身份运行).

You should also make sure you run Cygwin with elevated privileges (right-click the shortcut and choose Run as Administrator, or set the mintty shortcut property, Advanced → Run as Administrator).
