Broken package error refuses nix-shell launch #2

Closed pixln closed 4 years ago

pixln commented 4 years ago

While launching nix-shell, I receive the following error:

essence-of-live-coding-tutorial git:(master) nix-shell
..
error: Package ‘essence-of-live-coding-0.1.0.3’ in /nix/store/smvbabpccmq4xmk7c6r2jnhsxf73rbbh-nixpkgs-20.09pre237891.f9eba87bf03/nixpkgs/pkgs/development/haskell-modules/hackage-packages.nix:83143 is marked as broken, refusing to evaluate.

a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowBroken = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowBroken = true; }
to ~/.config/nixpkgs/config.nix.

(use '--show-trace' to show detailed location information)

Shall I follow one of the mentioned instructions?

@pixln I have a better option: Can you do git pull and try to launch nix-shell again?

Background

NixOS still thinks that these packages are broken although they are fixed since quite some time, afaikt. But that doesn't matter so much because that version is outdated anyways. I supplied the up-to-date versions in the nix shell now, so updating this repo should be fine.
