Bug on reinstallation about lorri HOT 6 CLOSED

Have you also removed the .lorri directory in your project’s root directory?

from lorri.

Yup, that did not change the error either unfortunately.

I checked with the debug command in the README as well, the output is the same..

Can you provide the shell.nix you're using, version of nixpkgs, etc?

from lorri.

Sure @grahamc, I have reproduced this error with two shell.nix files, and am using the following nix config:

The Haskell Project

This had a mostly untouched shell.nix created by cabal2nix:

(import ./. {}).grimoire-shell

The default.nix is:

{ compiler ? "ghc864", pkgs ? import <nixpkgs> {} }:

let

  haskellPackages = pkgs.haskell.packages.${compiler};
  drv = haskellPackages.callCabal2nix "grimoire" ./. {};

in
  {
    grimoire = drv;
    grimoire-shell = haskellPackages.shellFor {
      packages = p: [drv];
      buildInputs = with pkgs; [ cabal-install hlint ];
    };
  }

The Ruby Project

This is a bundix oriented setup, there is no default.nix and the shell.nix is:

{ pkgs ? import <nixpkgs> {} }:
let
    inherit (pkgs) ruby bundlerEnv mkShell bundler;
  env = bundlerEnv {
    name = "grimoire-bundler-env";
    gemfile  = ./Gemfile;
    lockfile = ./Gemfile.lock;
    gemset   = ./gemset.nix;
  };
in mkShell {
  name = "grimoire";
  buildInputs = with pkgs; [
# Not part of nanoc, needed for nokogiri
    zlib
    lzma
    gccStdenv
# Ruby and nanoc
    env
    bundix
    pandoc
  ];
}

Can you delete everything in /nix/var/nix/gcroots/per-user/YOUR_USERNAME/? That’s where lorri sets up its roots, maybe one of these is broken.

I mean in general we can’t anticipate every state a user puts their system into, this looks like a very special in-between state that you got because you reinstalled nix and lorri. It probably depends exactly on what you did when reinstalling nix (e.g. whether you removed the whole of /nix in the process or just parts of it).

Closing due to inactivity, feel free to ping for further questions.
