Guide: Fixing GHC version errors

VSCode Haskell extension might produce error and warning messages such as

Failed to find the GHC version of this Cabal project. Error when calling cabal exec -v0 -- ghc --print-libdir

and

I had trouble figuring out the exact GHC version for the project. Falling back to using 'ghc'.

while working on Juvix development.

These might stem from Cabal/Haskell version issues as well as the use of hie.yaml file through stack. Here is a quick guide how to fix these:

• Set the Haskell and Cabal versions to the relevant ones used by the Juvix team via ghcup tui

• Copy the stack.hie.yaml file, paste it in the same folder while renaming it to hie.yaml.

• Reload window
