rebol - cd 命令在 Red 中的相同上下文中表现不同

Question

查看最新行:从相同的上下文 %/C/目录，执行“cd rebol”在一种情况下有效，而在另一种情况下无效:

    >> what-dir
    == %/C/rebol/
    >> cd ..
    == %/C/
    >> what-dir
    == %/C/
    >> cd rebol
    == %/C/rebol/
    >> what-dir
    == %/C/rebol/
    >> cd /
    *** Script Error: / operator is missing an argument
    *** Where: catch
    *** Stack:  

    >> what-dir
    == %/C/rebol/
    >> cd ..
    == %/C/
    >> cd rebol
    == %/C/rebol/
    >> cd %/
    == %/
    >> what-dir
    == %/C/
    >> cd rebol
    *** Access Error: cannot open: %/rebol/
    *** Where: do
    *** Stack: cd change-dir cause-error

我现在不在 Windows 上，所以我无法测试它，但我相信这里有问题:

>> cd %/
== %/
>> what-dir
== %/C/
>> cd rebol
(...)

cd %/ 将目录更改为根目录，根据 what-dir 的报告，这绝对是 %/C/。所以我猜 what-dir 报告了错误的目录。稍后我会尝试添加信息，当我在 Windows 上检查它时，或者也许有人会更快并确认它:)您也可以尝试 read %/ 看看那里有什么(它应该是 Windows 驱动器 block )。
