Haskell無法加載模塊的接口

Question

您好，我正在嘗試在另一個模塊中使用一個模塊，但似乎無法正常工作。我嘗試更新cabal文件，堆棧，重新安裝了平台，ghc以及所有內容，但不允許它導入模塊。試圖在cabal文件中添加其他模塊和家庭模塊部分..無效，這可能是什么問題？

模塊：

module Test where


    test::IO()
    test=do
        elem<-getLine
        print elem


module Main where

import Test

main :: IO ()
main = do
  putStrLn "hello world"

Cabal-build呈現此錯誤：

當我使用Stack構建時，出現此錯誤：

    Use -v to see a list of the files searched for.

Answer 1

other-modules:指令必須位於Executable console節中。
