Have you tried 'stack exec -- ghci'? This way ghci should be able to find
the packages stack installed.

Hi all
I'm trying to follow this tutorial about lenses:
https://hackage.haskell.org/package/lens-tutorial-1.0.1/docs/Control-Lens-Tu...
Right at the top of the tutorial,it says do this in ghci:
import Control.Lens.Tutorial
I tried that, but I got an error: "Could not find module `Control.Lens.Tutorial'"
So I tried this:
D:\Sync\src\tutorials> stack install lens-tutorial Run from outside a project, using implicit global project config Using resolver: lts-6.9 from implicit global project's config file: C:\Users\dan\AppData\Roaming\stack\global-project\stack.yaml lens-tutorial-1.0.1: download lens-tutorial-1.0.1: configure lens-tutorial-1.0.1: build lens-tutorial-1.0.1: copy/register
I'm not exactly sure what that did, but it looked promising. However, I still get the same error in ghci as before when I do the import.
My question is, what do I need to do to get the import statement working in ghci so I can follow the tutorial? I would be grateful for any guidance. Thanks.
