[Nix-dev] Could not find module `Yi' (haskell editor)

[Cody Goodman]

I tried installing yi:

nix-env -iA nixos.pkgs.haskellPackages.yi

Then I made a config file at ~/.config/yi/yi.hs and opened it up. I
got an error that:

/home/cody/.config/yi/yi.hs:1:8:
    Could not find module `Yi'
    Use -v to see a list of the files searched for.

So I made a haskell source file that imported the Yi package and used
-v to compile it. I found these errors:



[cody at cody-nixos:~]$ cat helloyi.hs
import Yi

main = undefined

[cody at cody-nixos:~]$ ghc -v helloyi.hs  2>  err

[cody at cody-nixos:~]$ grep yi err
