I guess the issue was that before I wasn't creating an environment, because I wasn't using mkShell explicitely? These general nix questions are better in #nix:nixos.org, but to answer your questions derivations have to produce all outputs, of which out is mandatory. Your expression above did not create the output path expected so your got an error when you tried to build it. mkShell is a wrapper around mkDerivation that simply dumps some text into the output path (see pkgs/build-support/mkShell/default.nix). | 23:23:44 |

 Bruno Rodrigues | Ah great many thanks. I figured it had to do something with the fact that mkShell likely provided the required outputs, which I would have had to provide by hand otherwise | 07:52:14 |
| Bruno Rodrigues | I've joined the NixOS channel, I'll ask these types of questions in there in the future, thanks! | 07:52:56 |

| @petrichor:envs.net | ok, it's been a while since i looked at this, but i'm having a go at implementing a nix-flakes buildpack for repo2docker which will allow use of a git repo with a flake.nix on https://mybinder.org/ | 14:32:09 |
| @petrichor:envs.net | story so far is that i got it working 2 years ago using the existing nix buildpack and edolstra's flake-compat, and to prove the long-term reproducibility of nix, it still builds and runs using repo2docker! https://codeberg.org/jezcope/binder-nix-flakes | 14:34:22 |
| @petrichor:envs.net | hmm, OK, first roadblock to doing anything with a reasonably recent nixpkgs is this: repo2docker does not work with jupyter-server v2 https://github.com/jupyter-server/jupyter_server/issues/1038 | 16:24:45 |
| @petrichor:envs.net | is there a standard way to install an old version of a python package? equivalent to pip install jupyter-server<2.0.0 | 16:25:54 |
| @petrichor:envs.net | I guess I should ask in #python:nixos.org | 16:28:22 |
