Error while building a simplest app

[deemp]

Hi, @rikhuijzer! Trying to build my simple app to deploy to GH pages. Followed this example and succesfully built locally. But get such error on GitHub. Here's the text:

Do you have any idea how to fix this?

[rikhuijzer]

It looks like you're also installing Nix via cachix/install-nix-action

https://github.com/br4ch1st0chr0n3/try-ghcjs/blob/43d26a9ae0b87c67442129830db3166532d17f67/.github/workflows/main.yaml#L28-L33

while the instructions in the README of this repository are to only use rikhuijzer/cache-install. Then, this Action can handle the permissions when installing Nix.

Having said that, I'm trying to get it to work but don't have much success yet. I've removed the cachix/install-nix-actions and changed your default.nix to

let
  nixpkgs = builtins.fetchGit {
    url = "https://github.com/NixOS/nixpkgs.git";
    rev = "2291838453cd4fc3622aa73270390fc86c4ebf3e";
  };
in with (import (builtins.fetchGit {
  url = "https://github.com/dmjio/miso";
  ref = "refs/tags/1.8.2";
}) {});
pkgs.haskell.packages.ghcjs.callCabal2nix "try-ghcjs" ./. {}

but then nix-shell default.nix gives

error: builder for '/nix/store/7zn7jf9bqj207gwj5jmqvc25b7iwsaqm-ghcjs-base-01014ad.drv' failed with exit code 1;

I saw the same thing when running against NixOS stable in CI.

Thank you! Got a similar error when trying to follow nix's CI guide. That's, probably, a ghcjs problem. Maybe will just build js locally and then push
