I have a project in school where it is required to use
import Test.HUnit
I have installed it I cabal using
cabal install HUnit --lib
but when I try to run our code we get this error message:
Huffman.hs:8:1: error:
Ambiguous module name ‘Test.HUnit’:
it was found in multiple packages: HUnit-1.6.1.0 HUnit-1.6.1.0
My first thought was to try to delete one of the packages and they will therefore not overlap. But when I use:
cabal list --installed
I cannot find the HUnit package. How can I delete it if I cannot find it??
(I am a beginner at Haskell and in programming in general)
