I'm currently reading "Haskell: the Craft of Functional Programming", by Simon Thompson and I'm trying to download and install the package books code. But when I run "stack build Craft3e" I get the following error message:
Run from outside a project, using implicit global project config Using resolver: lts-5.12 from implicit global project's config file: > /home/dumbl3d0re/.stack/global-project/stack.yaml While constructing the BuildPlan the following exceptions were encountered:
-- Failure when adding dependencies: HUnit: needed (==1.2.*), 1.3.1.1 found (latest applicable is 1.2.5.2) mtl: needed (>=1.1 && <2.2), 2.2.1 found (latest applicable is 2.1.3.1) needed for package Craft3e-0.1.0.10
How should I go about to install "Craft3e"? Thanks in advance! Regards, Albin
