Question

我一直试图通过doctest进行单元测试。得到错误：

hs-procr-0.1.0.0: test (suite: hs-procr-test)

Progress: 1/2
<interactive>:5:14: error:
Ambiguous occurrence ‘stdout’
It could refer to either ‘Turtle.stdout’,
                         imported from ‘Turtle’ at app/Main.hs:7:1-13
                         (and originally defined in ‘Turtle.Prelude’)
                      or ‘System.IO.stdout’,
                         imported from ‘System.IO’
                         (and originally defined in ‘GHC.IO.Handle.FD’)

我不知道为什么;我的所有*.hs个文件都已

import System.IO hiding (FilePath, stdout, stderr)

package.yaml：

...
tests:
  hs-procr-test:
    main:                Spec.hs
    source-dirs:         test
    ghc-options:
    - -threaded
    - -rtsopts
    - -with-rtsopts=-N
    dependencies:
    - hs-procr

Spec.hs：

module Main (main) where

import Test.DocTest
import System.IO hiding (FilePath, stdout, stderr)

main :: IO ()
main = doctest [ "app/Main.hs"
               ]

我使用stack，没有* .cabal文件。我错过了什么？

Main.hs：

{-# LANGUAGE OverloadedStrings #-}
module Main ( main
            , strStripNumbers
            ) where

import Lib
import Turtle
import Prelude hiding (FilePath)
import System.IO hiding (FilePath, stdout, stderr)
import Text.Regex.TDFA
...

模糊发生'stdout'
