I'm trying to follow this tutorial about lenses:
Right at the top of the tutorial,it says do this in ghci:
I tried that, but I got an error: "Could not find module
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:
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.
