Install GHC (Glasgow Haskell Compiler)

We use GHC as the Haskell compiler and interactive environment for Haskell. GHC is an open-source project and its earliest prototype was created at the University of Glasgow.

Install GHC. We recommend the automatic official installation script you can run with the command shown on this page. All the default choices are fine for our purposes. (Installing it via Homebrew is also possible, but less recommended.) The installation of the compiler and the related tools may take a while.

Which version of GHC are you running?

Run ghc --version to find out, and copy its output here:
