Первый раз пытается использовать зависимость с Кабал

Выполнить команду инициализации в локальной папке SparkSetup:Первый раз пытается использовать зависимость с Кабал

cabal init

Это создает следующие файлы:

SparkSetup.cabal:

Setup.hs:

import Distribution.Simple 
main = defaultMain

Затем я изменить мой Setup.hs файл включить модуль Network.Download из https://hackage.haskell.org/package/download

Setup.hs:

import Network.Download 
import Distribution.Simple 
main = defaultMain

И затем выполнить команды:

cabal sandbox init 
cabal install -j

Но сообщение об ошибке:

Похоже, что пакет 'download' основан на заголовках систем, предоставляющих макрос' __BEGIN_DECLS'. Я думаю, это никогда не тестировалось в окнах. – melpomene

@melpomene вы можете посоветовать, какую ОС я должен использовать для Haskell dev. Ubuntu? –

Я бы использовал какой-то Linux, да. Я не знаю, какое распространение лучше всего подходит для Haskell. – melpomene

Вы обычно не трогают Setup.hs вообще.

Вместо этого добавьте download в поле build-depends в ваших .cabal файлах.

Кроме того, файл .cabal является неполным: раскомментируйте поле main-is и введите имя файла вашего основного модуля, например.

main-is: SparkSetup.hs

Breitner so line build-depends: base> = 4.7 && <4.8 следует строить-зависит: base> = 4.7 && <4.8 && скачать? –

'base> = 4.7 && <4.8, download' –

см. Вопрос об обновлении, пакет загрузки не устанавливается? –
