Haskell: Problem Importing System.Random Windows

I've been trying use the System.Random library but keep getting the error

    Could not find module `System.Random'
    Use -v (or `:set -v` in ghci) to see a list of the files searched for.

    import System.Random

I've installed random with cabal (cabal install --lib random) and in powershell it says that everything is up to date. I've tried installing stack to fix the problem but have come across a lot of problems doing that.
