Hello! I’m trying to add servant-ghcjs-client to my Haskell project. This package is not in Hackage, but it is within the servant git repo: servant/servant-client-ghcjs at master · haskell-servant/servant · GitHub
Below, I’ve included the error output when running nix-build as well as both nix files and the cabal file.
Any tip you may have is very much appreciated!
The error:
$ nix-build
