在Purescript repl中导入Data.Path模块失败

Question

我试图在purescript中导入Data.Path模块，但是出现了以下错误

Error found:
in module $PSCI
at <internal> line 0, column 0 - line 0, column 0

   Unknown module Data.Path


See https://github.com/purescript/documentation/blob/master/errors/UnknownName.md

我应该安装哪些软件包才能发出以下命令：

$ pulp repl
> import Data.Path

> root
/

> isDirectory root
true

> ls root
[/bin/,/etc/,/home/]

提前感谢。
