Getting could not find module despite successful build with packages. The module is QuickCheck

package.yaml :

executables:
  wk4-exe:
    main: wk4.hs
    ghc-options:
    - -threaded
    - -rtsopts
    - -with-rtsopts=-N
    dependencies:
    - QuickCheck

stack.yaml :

resolver: lts-14.27

packages:
- .

extra-deps: 
- QuickCheck-2.13.2

Can you output the contents of the Haskell tab from the Output window in VS Code?

If you are seeing this in a terminal, you probably should have run ghcide WITHOUT the --lsp option!

Output from setting up the cradle Cradle {cradleRootDir = "f:\\Users\\Ratanak\\School\\UNI\\CS3141_2020", cradleOptsProg = CradleAction: Default}

The project discovery has failed you!
Let's take a look at the cradle: (which tells hls where your root directory is and which tool (cabal/stack) it should use to load your project)

Cradle 
  { cradleRootDir = "f:\\Users\\Ratanak\\School\\UNI\\CS3141_2020"
  , cradleOptsProg = CradleAction: Default
  }

Is the path "f:\\Users\\Ratanak\\School\\UNI\\CS3141_2020" the root of your project? Is your stack.yaml in the same directory?
The record cradleOptsProg should have the value CradleAction: Stack, that's how you know it configures your project correctly!

On windows, I usually use Open Folder and open exactly the folder that contains my project.

No it is not. It is a few more folders in. I will try to replicate the open folder.
But I found a workaround by having a hie.yaml in the root of the project folder.

It seems this is not a bug. but hie-bios behaviour, so i am gonna close it. @ratanakkim please reopen if you think something could be improved
