Haskell parse error on input

Question

I'm new to haskell, and I'm trying to play around with some modules. I wrote this very basic module:

module Cube
(
    cubeArea
) where

cubeArea :: Float -> Float
cubeArea sideSize = sideSize * sideSize * sideSize

in a file named "Cube.hs". Then, I opened ghci in the cmd in the same folder the Cube.hs is. Now, when I type import Cube.hs, I get this error:

:26:8: error: parse error on input `Cube.hs'

Any idea why?

Answer 1

Start GHCi:

• ghci Cube.hs
• stack ghci Cube.hs

While already in GHCi:

• :l Cube.hs or :load Cube.hs
• :r Cube.hs or :reload Cube.hs
