Я пытаюсь использовать этот проект: https://github.com/mpickering/old-ghc-nix
Я предполагаю, что должен 'импортировать' ghc.nix (который генерирует деривацию?):
shell.nix :
with (import <nixpkgs> {});
# let ghc = nur.repos.mpickering.ghc.ghc841;
let ghc = import /home/chris/temp/old-ghc-nix/ghc.nix;
in haskell.lib.buildStackProject {
inherit ghc;
name = "myEnv";
buildInputs = [ pcre ];
}
Однако это дает мне ошибку:
...
error: cannot coerce a function to a string, at /home/chris/fromLaptopt/usbflash/Haskell/CeriumYankeeAvocado/shell.nix:6:3
...
Как мне «выполнить» функцию / построить деривацию?
