direnv: loading ~/app/.envrc
direnv: using flake . --impure
The directory referred to contains a Gemfile and a Gemfile.lock. Interestingly, this worked before I updated flake inputs earlier today.
Rolling back fixes things. These versions work as expected with the aforementioned flake.nix.

Hmm, I'm trying to make bundix work, but it's failing to generate gemset.nix.
Probably not what you're after, but I could get it to work with devenv.sh without bundix:
$ devenv init
$ echo 3.3.0 > .ruby-version
devenv.nix:
{ pkgs, ... }:
{
languages.ruby = {
enable = true;
versionFile = ./.ruby-version;
};
}devenv.yaml:
inputs:
nixpkgs:
url: github:NixOS/nixpkgs/nixpkgs-unstable
nixpkgs-ruby:
url: github:bobvanderlinden/nixpkgs-ruby
inputs:
nixpkgs:
follows: nixpkgs$ bundle init
$ bundle add rails
$ rails new blog
$ cd blog
$ rails server
If bundix is the issue, could you create a gist with all files included, so that I can reproduce the issue?
Apologies for the slow response, Bob, and thank you for your help.
I've pushed a minimal reproduction: https://github.com/jcf/nixpkgs-ruby-111
Edit: Just to explain why I'm jumping through these hoops, the use of plain devenv will make installing Rubygems like pg and nokogiri tricky as they depend on C, etc. It's only with an explicit version of Ruby configured via the .ruby-version file and Bundix that I've been able to reliably install a set of realistic Rails dependencies.
If you rely on a .ruby-version file in your Gemfile, you have to inform bundlerEnv via extraConfigPaths like so:
gems = pkgs.bundlerEnv {
name = "nixpkgs-ruby-111-gems";
gemdir = ./.;
groups = ["default" "development" "production" "test"];
extraConfigPaths = [ "${./.}/.ruby-version" ];
};With that extraConfigPaths in place, the Gemfile in one's Nix store has its .ruby-version file alongside.
Ah that is new for me. Thanks for the feedback 👍
The documentation of nixpkgs does indeed mention this solution: https://github.com/NixOS/nixpkgs/blob/master/doc/languages-frameworks/ruby.section.md#using-an-existing-gemfile-using-an-existing-gemfile
Still a bit surprising it is needed. Hopefully a future reader will be helped with this issue 👍

My thoughts exactly! Thanks for the assist, Bob.
