hie-wrapper fails with "couldn't find a HIE binary with a matching GHC version"
JonathanReeve opened this issue · 4 comments
After following the instructions in the README here, and using this line in my home.nix: (all-hies.selection { selector = p: { inherit (p) ghc864 ghc843; }; })
and this project default.nix:
let
pkgs = import <nixpkgs> { };
in
pkgs.haskellPackages.developPackage {
root = ./.;
modifier = drv:
pkgs.haskell.lib.addBuildTools drv (with pkgs.haskellPackages;
[ cabal-install
ghcid
]);
source-overrides = {
plotlyhs = builtins.fetchTarball "https://github.com/JonathanReeve/plotlyhs/archive/0fcf833.tar.gz";
};
}
Running hie fails with this error:

I'm guessing this is because of #55, for not supporting 8.8.3? Or is it something else?
If hie-wrapper doesn't support 8.8.3, is there a way I can downgrade my haskellPackages version, using that default.nix, so that I can use 8.8.2 instead?
Indeed, that's because 8.8.3 isn't supported by the HIE version in all-hies. Until that's sorted out, I think the best way to get around this is to downgrade to a nixpkgs whose default GHC version is 8.8.2 (to avoid having to rebuild everything).
From the nixpkgs master build history at https://hydra.nixos.org/job/nixos/trunk-combined/nixpkgs.ghc.x86_64-linux, it looks like nixpkgs revision 0eb0ddc4dbe3cd5415c6b6e657538eb809fc3778 is a good candidate for this
Ah I see. Do you know where I can find a guide on how to downgrade my nixpkgs version?
I suggest pinning the nixpkgs in your projects like this: https://nixos.wiki/wiki/FAQ/Pinning_Nixpkgs
Awesome, thanks! I'll close this as a duplicate.
