These are my notes step by step to install haskell development kit on OSX.
- Ensure your haskell installed from https://ghcformacosx.github.io/
- Install haskell plugins from your Intellij plugins installation menu.
After that we need install some package thru cabal (Haskell build tools)
$ cabal update && cabal install ghc-mod
Go back to intellij idea, select “Preferences > Language & Frameworks > Haskell”
then adjust with your configuration below.
Update 30 August 2016:
Sometime you will get error once you installing “ghc-mod”, because I’m installing on another laptop and got this error.
cabal: Error: some packages failed to install: ghc-mod-220.127.116.11 depends on haskell-src-exts-1.17.1 which failed to install. haskell-src-exts-1.17.1 failed during the configure step. The exception was: ExitFailure 1 hlint-1.9.35 depends on haskell-src-exts-1.17.1 which failed to install.
I fix this issue by installing “haskell-src-exts-1.17.1″ manually, but don’t forget to install “happy” because it’s required to install “haskell-src-exts”.
$ cabal install happy $ cabal install haskell-src-exts-1.17.1 $ cabal install ghc-mod # continue the ghc-mod installation.
