Couldn't execute ghc --print-libdir

Dear all
Im running vscode on windows10.

I have installed the Haskell installer for windows from the official website
(https://docs.haskellstack.org/en/stable/README/#how-to-install)

I have also installed the haskell extension pack on my vscode.

Now im getting an error as shown in the photo. Please help and thank you so very much.

Do you have system GHC installed? If not, you need a stack project (with stack.yaml) in order to use GHC installed by stack.

Hi Ailrun
Thanks for the help. I am new to Haskel. Would you please elaborate on " a stack project (with stack.yaml)" ? Thank you so much

@z5230445 I assume that your directory does not have any project configuration, i.e., it's just with *.hs files. Without System GHC (installed in your %PATH%), the current HLS does not support such a case. You need either

• To install a system GHC (using choco package manager or similar)
• To add a project setting for your directory

For the project setting, you need stack.yaml and one of <your project name>.cabal/package.yaml. You can create those files using stack new command with a template (listed here), or you can create package.yaml by hand based on info in https://github.com/sol/hpack and then use stack init.

For completeness the issue tracking support for this case is: #692
