getting ghcide error #12

Closed FrankC01 closed 3 years ago

FrankC01 commented 3 years ago

I followed these steps:

git clone https://github.com/jonascarpay/template-haskell first-app
cd first-app
./wizard.sh
nix-shell
cabal new-build 
code .

And in code I am getting: 

This is unsupported, ghcide must be compiled with the same GHC version as the project.

What happens when you run haskell-language-server in the shell? If that runs without any problems, the issue has to be that your VS Code is not picking the right executable. In particular, it seems it's using some ghcide, rather than the haskell-language-server in your PATH..

First note is the exception shown at the beginning of haskell-language-server

But what I did after that, which seems to be working, was:

which haskell-language-server
/nix/store/j8xivmf4j6xmsvq32g86029sh1m2adhj-haskell-language-server-exe-haskell-language-server-1.0.0.0/bin/haskell-language-server

I took that output and put it in vscode settings:Haskell: Server Executable Path which seems to now work.

jonascarpay commented 3 years ago

Your haskell-language-server output looks normal, no issues there.

I'm glad you found something that works, but be aware that this is a fragile solution; you're pinning an exact path in the nix store. Any change in dependencies/versions will change this path and might then cause unexpected breakage after a garbage collect. I'm not familiar with VS Code, but I imagine there should be some way to get it to automatically pick up HLS from PATH. What happens if you set the executable to just haskell-language-server?

FrankC01 commented 3 years ago

I hit that thought earlier today, re-installed Nix and vscode extensions and left everything vanilla and is holding strong. Not sure what I did differently earlier that would cause it to go sideways.

Haskell, Nix and Cabal are all new to me so I'm fairly certain I dropped an egg or two....

Thanks!
