command <.../nix> failed with exit code 1 when running devenv init or devenv shell

[sonn-gamm]

Describe the bug

Full error log:

Error:   × Command `/nix/store/7h693862idwiqjyim0sn2n4jmf4rpgpa-nix-2.21-devenv/bin/nix --show-trace --extra-experimental-features nix-command --extra-experimental-features flakes
  │ --option warn-dirty false --option eval-cache false --keep-going --max-jobs 4 print-dev-env --profile /Users/<paths>/.devenv/gc/shell` failed with with exit
  │ code 1

To reproduce

I upgraded from devenv 0.6 to devenv 1.0.4 and got this error when running devenv shell as usual in an existing project. I thought there could be incompatibility between breaking releases so deleted all devenv files except devenv.nix. Running devenv shell with this devenv.nix produced the above error:

{ pkgs, ... }:

{
  packages = [
    pkgs.python311Packages.pip
    pkgs.nodejs
    pkgs.nodePackages.typescript
    pkgs.nodePackages.prettier
    pkgs.cloud-sql-proxy
  ];

  languages.python = {
    enable = true;
    venv.enable = true;
    package = pkgs.python311;
  };

}

Running devenv init in a folder with no devenv files produced the same error.

Version

devenv 1.0.4 (x86_64-darwin).

Did you get any output? Can you run the given command to see what it will return?

[sonn-gamm]

This is the full output. Besides, devenv creates the following files / folders:

• .devenv
• .devenv.flake.nix
• .envrc
• devenv.lock
• devenv.nix

[domenkozar]

@sonn-gamm did you add devenv.nix with git add?

[sonn-gamm]

@domenkozar devenv.nix is not tracked to the git repo. would that be a problem? for the last 9-12 months of usage of devenv it's never been a problem.

[domenkozar]

@sonn-gamm can you try devenv 1.0.3?

[ahansen90]

I'm having this exact same issue. Tried with every version of devenv that has been on nixpkgs. Same issue.

[sonn-gamm]

i just tested devenv 1.04 in a different project repo and it worked!

in this case i did not nuke every devenv related file and folder to start from scratch, but simply cded into the project folder and ran devenv shell.

at the end of the process devenv told me i should update devenv, eg:

✨ devenv 1.0.4 is newer than devenv input in devenv.lock. Run `devenv update` to sync.

this is my devenv.lock before i'm going to maybe upgrade (maybe because it might break things):

Can others confirm too?

Update: I had devenv.nix (and all other devenv files) in .git/info/exclude (since I don't want to commit my personal config that no one else is using), which seemed to be causing the issue. If I remove it from there, it works as expected.

I had this same setup on 0.6.3 which was working, so it would seem it's probably some change since then.

1.0.5 should allow that :)
