编辑：经过大量的Google搜索，找到了here

尝试在Windows上使用部署资源失败：   symlink（）函数在此机器上未实现（NotImplementedError）   这是因为Ruby的底层File.symlink（）方法不支持Windows。

在短期内，这应该在文档中提到。从长远来看，我认为这可以通过＆＃34;链接＆＃34;指令有效。由于NTFS的限制，此方法可能不适用于软链接。

所以，它肯定是Windows特定的，但想知道为什么没有其他帖子或链接解释它与Windows不兼容。 Windows 中的此可修复不是吗？

Answer 1

这是有争议的，但有人说symlinking已在Ruby 2.3上实现。我会先尝试安装它。

symlink（）NotImplementedError rabl
