Can you post the content of /tmp/hie.log?

[fendor]

Also: No System GHC found
Do you have a ghc installed? Can you post the project somewhere?

[sashasashasasha151]

Can you post the content of /tmp/hie.log?

Already in description

Do you have a ghc installed? Can you post the project somewhere?

Yes, I added paths to .bash_profile using export
Any project, stack new my-project for example

[fendor]

So, no message haskell-lsp:Starting up server ... in /tmp/hie.log?
What happens, if you manually execute the path /nix/store/gabld13fzhqix3mcv3f0bl0vk3y6kq64-haskell-ide-engine-combined/libexec/bin/hie?

[sashasashasasha151]

no message

no

manually execute the path

hie-wrapper couldn't find a HIE binary with a matching GHC version in your all-hies installation

But in atom I also have this message

[fendor]

That sounds weird, hie is not hie-wrapper? Afaik, this message is only emitted by hie-wrapper. On my system, ${haskell-ide-engine}/libexec/bin/hie is not executable...

I had similar issue, i think ghc 8.6.4 is not available on your machine. what is the output for ghc --version, you can install ghc using nix nix-env -i ghc or ghcup

[sashasashasasha151]

output for ghc --version
8.6.4

I tried other ghc versions and also in Atom all works fine

[yuanw]

the message is emitted at here, what is the output if you run hie-8.6.4 directly?

[sashasashasasha151]

It starts

[Infinisil]

@fendor all-hies has a special custom setup for how the binaries are organized. The hie binary that throws this

hie-wrapper couldn't find a HIE binary with a matching GHC version in your all-hies installation

message exists to prevent infinite loops in case people have hie (=hie-wrapper) in their PATH, so hie-wrapper would call itself because it can find itself as a hie binary.

@sashasashasasha151 It seems that vscode doesn't have GHC on its PATH, can you verify that in vscode's shell?

If it helps, I just encountered the same issue (WSL, using VSCode with the WSL plugins, hie/ghc installed with nix). What happened in my case was that I launched code . from the bash shell, but in VSCode it picked up zsh I had installed and set as the default shell. It did not have ghc in path. I uninstalled zsh and now everything works great!

Closing since this is using an old mechanism and could be closed already. Feel free to open again with fresh information!
