Lorsque j'essaie d'installer Haskore, avec cabal, j'obtiens le conflit de dépendance suivant. (J'ai GHC 8.0.1)Installation de Haskore avec cabal

Comment puis-je résoudre ce problème?
Vous pourriez peut-être essayer de l'installer avec pile au lieu de cabale. –
@Chris Cela ne serait d'aucune aide, car [Haskore n'est pas dans un instantané de Stackage] (https://www.stackage.org/package/haskore). La pile peut être utile dans de nombreuses situations, mais ce n'est pas une solution miracle. – duplode
