• VSCode-Haskell: v2.2.0
• GCHup 0.1.17.7
• HLS 1.7.0.0
• GHC 8.10.7

Steps to reproduce

• Add VSCode-Haskell to VSCode
• Use GHCup to install Haskell toolchain
• Extend the path for haskell as described
• Open a Haskell project in VSCode

Expected behaviour

• Getting hints/lints/fmt and all the other goodies

Actual behaviour

I get an error message that starting the client failed.

Server logs:

Try with an explicit cradle as file hie.yaml in your project with the following contents:

Try with an explicit cradle as file hie.yaml in your project with the following contents:

Neither hie.yaml, nor hie.yml work. Do I need to fill the cabal field somehow?

Can you be more specific? What's the error?

Can you be more specific? What's the error?

The same as above in VS Code:

2022-05-07 22:37:33.9270000 [client] INFO Starting language server
[Error - 23:37:33] Starting client failed
Launching server using command haskell-language-server-wrapper failed.

In the terminal however:

Failed to get project GHC version: CradleError {cradleErrorDependencies = [], cradleErrorExitCode = ExitFailure 1, cradleErrorStderr = ["Error when calling cabal exec -v0 -- ghc --print-libdir","","No cabal.project file or cabal file matching the default glob './*.cabal' was found.\nPlease create a package description file <pkgname>.cabal or a cabal.project file referencing the packages you want to build.\n\n"]}

It might be useful to know that I am not trying to create a bigger project, just playing around with Haskell.

You haven't created a project. Follow https://www.haskell.org/ghcup/steps/#creating-a-proper-package-with-modules
