Проблемы с установкой модуля в Haskell

Question

Я пытаюсь установить HDBC и HDBC.odbc для проекта на Haskell. Я скачал модули и необходимые зависимости от Hackage и установил их с cabal install [module name]. Хотя мне нужно было использовать Cygwin для зависимостей convertible и utf8, поскольку я работаю в Windows.

Когда я звоню cabal list --installed, я получаю

.cabalБиблиотека и исполняемый файл для проекта выглядят следующим образом:

Но модули по-прежнему не распознаются в проекте.

module Main where

import Database.HDBC
import Database.HDBC.ODBC

main :: IO ()
main = do

Could not find module `Database.HDBC'
Could not find module `Database.HDBC.ODBC'

У меня есть модули в отдельном каталоге,но я попытался поместить их непосредственно в один и тот же каталог, но безуспешно, поэтому я не был уверен, было ли это необходимо или нет ..

Я довольно новичок, и это первый раз, когда я имел дело симпортировать модули, как это. Я выполнил большой объем поиска, но не нашел успеха в руководствах или в проблемах, которые я мог бы найти, похожих на мои.

Если это помогает по какой-либо причине, я использую Haskero в VSCode с Windows 10.
