wrong hash for google-protobuf-3.23.3

[brianmay]

Gemfile:

source 'https://rubygems.org'

gem 'jekyll'

gem "html-proofer"

group :jekyll_plugins do
      gem 'RbST'
      gem 'jekyll-paginate'
      gem 'jekyll-environment-variables'
end

flake.nix:

{
  description = "Brian's website";

  inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-23.05";
  inputs.flake-utils.url = "github:numtide/flake-utils";

  outputs = { self, nixpkgs, flake-utils }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = nixpkgs.legacyPackages.${system};

        # Generate a user-friendly version number.
        version = builtins.substring 0 8 self.lastModifiedDate;

        gems = pkgs.bundlerEnv {
          name = "gems";
          ruby = pkgs.ruby;
          # gemfile = ./Gemfile;
          # lockfile = ./Gemfile.lock;
          # gemset = ./gemset.nix;
          gemdir = ./.;
        };

      in {
        packages.default = pkgs.stdenv.mkDerivation {
          name = "penguin_brian-${version}";
          src = ./.;
          buildInputs = [ gems ];
          buildPhase = ''
            export VCS_REF="${self.rev}"
            export BUILD_DATE="${version}"
            ${gems}/bin/jekyll build --destination _site
          '';
          installPhase = ''
            mkdir -p $out
            cp -r _site $out/_site
          '';
        };
        devShells.default =
          pkgs.mkShell { buildInputs = [ gems pkgs.bundix ]; };
      });
}

Script for testing:

#!/bin/sh
set -ex
rm gemset.nix Gemfile.lock
nix-shell -p bundler --command "bundle install"
nix-shell -p bundix --command "bundix -l"
nix shell

Gives:

+ nix shell

I actually run into this too.

Work around is:

BUNDLE_FORCE_RUBY_PLATFORM=true nix run 'nixpkgs#bundix' -- --lock

I believe these issues are the same (although there are very different symptoms):

• "Could not find nokogiri..." when starting a new Rails project on macOS 11.4 #88
• nokogiri build failure when building ruby+rails environment NixOS/nixpkgs#190084

[brianmay]

Correction: appeared to work initially, but got the nokogiri build error back again.

I am hitting this too; just upgraded from an old version.

Very unfortunate.

I face the same issue with the sqlite3 gem included in the vanilla Gemfile from the rails new <project-name> command

error: hash mismatch in fixed-output derivation '/nix/store/wnx60m5zmhq2gnzwgd1nrr83nkrjf8wi-sqlite3-1.7.3.gem.drv':

edit: considering the state of the project, I'd suggest using devbox instead
