This should be fixed by #1592

[peterbecich]

I think this still occurs:

https://github.com/peterbecich/haskell.nix-ghcjs-issue/blob/fa6a9231ad133ddaa668e96679465282af3d4737/nix/hix.nix

with compiler-nix-name = "ghc924";

$ nix develop

With compiler-nix-name = "ghc902"; the issue does not occur, and nix develop succeeds

[peterbecich]

@br4ch1st0chr0n3 , for me this error disappeared with nix flake update.

Now nix develop works. Here is HLS:

@hamishmack @yvan-sraka , can this be closed?
