HLS does not support GHC 9.2.5 yet.

That sounds like you try to use this extension with an unsupported GHC version, in particular 9.2.5. Be sure to consult the docs to see which ghc version are currently supported: https://haskell-language-server.readthedocs.io/en/latest/support/ghc-version-support.html

Switch to an older ghc version, for example via ghcup in powershell:

> ghcup install ghc 9.2.4
> ghcup set ghc 9.2.4

Ideally, then the extension should work out of the box.

Unfortunately, it still doesn't. Personally, HLS Extension in VS Code returns "Failed to find a HLS version for GHC 9.2.5 Executable names we failed to find: haskell-language-server-9.2.5,haskell-language-server" Do you know, how to fix this problem?

[fendor]

Please follow the instructions here: https://github.com/haskell/vscode-haskell#investigating-and-reporting-problems

and provide the logs, so we can take a look.

[sburan]

Should I include the whole output? I figured till here is the actual interesting part. I'm not quite sure why it is still looking for an executable 9.2.5, when I've already globally set to 9.2.4

Maybe this is a stack project? Like, is there a stack.yaml in your project?

[sburan]

Yes there is. I create projects with stack new and stack build in the folder. Before HLS worked perfectly in VS Code, when i opened the folder. After using "stack init" once it automatically updated to ghc 9.2.5 and led to this issue, unfortunately. I orginally installed all with GHCup.

Re-run the GHCup bootstrap script. It will ask you if you want to enable better stack integration. Answer with YES. Then make sure your stack config does NOT say system-ghc: true.

[sburan]

@hasufell So I just re-run the bootstrap where I agreed to all the questions. In my project I run the command "stack config set system-ghc false", but in VS Code is still tells me that it failed to find a HLS Version for GHC 9.2.5.

[hasufell]

Share your entire project and your ~/.stack/config.yaml and your ~/.stack/hooks/ghc-install.sh.

[sburan]

@hasufell hi! i haven't changed any of them manually before files.zip

[fendor]

@sburan Still an issue? I just noticed, we haven't come back to you.
