Whenever I'm running any command that includes cabal-dev, I'm getting the following error:
cabal-dev: command not found
I've downloaded cabal-dev package from
http://hackage.haskell.org/package/cabal-dev
But there are no instructions on how to install it.
It has something to do with MacOS. This command solved the problem.
cabal install gtk -fhave-quartz-gtk
