Haskell after install the conduit package

Question

I`m new in the Haskell and do the task for my class. I install it in VSCode, downloaded the extension for it and everything works fine. But after installing the Conduit library I get this error:

ghc-9.4.7.exe: C:\cabal\store\ghc-9.4.7\hashable-1.4.3.0-1961fe79003fd705645c177b7f4aca0399a4d276\lib\libHShashable-1.4.3.0-1961fe79003fd705645c177b7f4aca0399a4d276.a(#7:LowLevel.o): Not a x86_64 PE+ file.

Can you help me with it? Thank you in advance)

Answer 1

(Not an Answer) I have the same problem on Windows 10. I just did a fresh (and first time) install of GHCup following all the default instructions from the page https://www.haskell.org/ghcup/

Then I started following the First steps instruction from https://www.haskell.org/ghcup/steps/ (Yes I'm new too...)

But everything starts to slip when I reached the section: Using external packages in ghci

Trying the cabal-install command: cabal repl --build-depends asyn I ended up with the following:

I:\DevData\Haskell\test-cabal>cabal repl --build-depends async

In order, the following will be built (use -v for more details):

cabal-3.6.2.0.exe: repl failed for test-cabal-0.1.0.0.

I:\DevData\Haskell\test-cabal>cabal --version
cabal-install version 3.6.2.0
compiled using version 3.6.2.0 of the Cabal library

Issue obviously seems to come from the hashable-1.4.3.0 module (not a x86_64 PE+ file) in both case.

Answer 2

I had the same issue and fix it with flowing:

1) Install hshashable and conduit

cabal install hashable  
cabal install conduit

Then for using conduit in GHCi run:

cabal install --lib hashable
cabal install --lib conduit

2) In case version issue Check GHCi and Cabal versions:

https://www.haskell.org/cabal/download.html For update cabal use command:

ghcup install cabal 3.8.1.0
