flake is not a recognized command #315

Possible Solution

I think either I met something up on my end or there was a update to flakes it broke things.

Steps to Reproduce

The above should work for this.

Context

I was trying to update to the latest devos and thought it was maybe a peculiarity of my set up. So I tried just following the guide to rule that out, and it appears there's some other issue.

codygman · 2021-06-12T18:08:57Z

It looks like I can get around this by just calling nix-shell.

jojosch · 2021-06-12T18:21:41Z

I had the same issue yesterday after updating - resolved it by adding an overlay for nix-direnv which sets enableFlakes=true.

Thats because NixOS/nixpkgs#126137 disabled flake support in nix-direnv by default - and that change is present in your current version 432fc2d.

codygman · 2021-06-12T18:39:44Z

In case anyone else needs it, this took a few minutes to remember:

 }

NOTE: Make sure you've added the overlay to git

codygman · 2021-06-12T22:51:18Z

This is fixed for me in, but perhaps this should be the default?

blaggacao · 2021-06-13T03:24:23Z

Thank you both for report and solution.

This is fixed for me in, but perhaps this should be the default?

It should, but unfortunately this would be harmful for older nixpkgs versions. I think there is no way around using builtins.functionArgs to peak the function and check for the availability of enableFlakes.

Does the override function expose the original package functions args?

Along those lines?

if ((builtins.functionArgs prev.nix-direnv.override) ? enableFlakes or null) != null then prev.nix-direnv.override { ... } else prev.nix-direnv

If you have an itch for a PR, please feel free to submit one to master. 😉

fixes #315

andrevmatos · 2021-06-15T19:07:58Z

The issue re-appeared for me after today's lock update, even with above fix.

jojosch · 2021-06-15T19:25:21Z

I did update now as well and can confirm that with the current workaround and an updated home-manger the error reappears. See nix-community/home-manager@e0f2949 for the change.

Now programs.direnv.enableNixDirenvIntegration = true; needs to be "replaced" with programs.direnv.nix-direnv.enable = true; and programs.direnv.nix-direnv.enableFlakes = true; when using home-manager after the above mentioned commit.

blaggacao · 2021-06-15T21:16:47Z

I see. @Pacman99 Do we have "overlays" for home manager? I think the actual fix could be quite similar ...

codygman · 2021-06-15T21:45:06Z

Could this error be related to the overlay issues fixed by #55?

Pacman99 · 2021-06-15T22:37:31Z

I see. @Pacman99 Do we have "overlays" for home manager?

I mean any nixpkgs overlay for the host's channel will be applied for the nixpkgs passed to home-manager since it just inherits from the host.
If your talking about the module option, we could do something like this in the direnv profile:

{ config, ... }:
{
  programs.direnv.nix-direnv.enable = config.programs.direnv.enableNixDirenvIntegration;
}

blaggacao · 2021-06-16T13:58:34Z

I guess we need to conditionally enable
programs.direnv.nix-direnv.enableFlakes = true; only for hm versions that have this option.

codygman · 2021-07-26T16:20:07Z

This is still broken for me... I think. Maybe it's a separate problem but now I'm getting:

Did you ever find a fix for this? Stuck on the EXACT same problem right now! :(

Pacman99 · 2021-12-29T22:20:28Z

nix-direnv flakes support should be fixed, so I'm going to close this. The latest problem can be tracked in #406

ParetoOptimalDev · 2022-03-14T04:38:53Z

Using the example in divnix/digga as of 396b04b this error still happens:

❯ cd examples/devos/
direnv: loading ~/code/digga/examples/devos/.envrc
direnv: using flake

I thought maybe my personal flake was the issue, but it's the same as the one in the example/devos/flake.nix and my direnv is the same as example/devos/flake/users/profiles/direnv.

ParetoOptimalDev · 2022-03-14T05:10:14Z

All of my issues were caused by a typo in:

- bud.localFlakeClone = "/home/nixoss/system";
+ bud.localFlakeClone = "/home/nixos/system";

ParetoOptimalDev · 2022-03-14T17:40:12Z

Apparently not, I use the system installed (from bud switch) bud version rather than direnv giving me the shell version.

I have to use nix develop to get the correct one.

Maybe my install somehow got in s bad state?

I'll create a VM from the Bud devos example and see if I can reproduce this issue later

DrPyser · 2022-04-28T20:36:50Z

I'm also experiencing this issue. Maybe it's worth reopening?
It's unclear to me what should be the nix version used by the flake devShell, and how to explicitly configure it.
My system configuration uses nix 2.7

> readlink (which nix)
/nix/store/7gjn39gw0dli14vvwm7bqy99dljw3b2z-nix-2.7.0/bin/nix

. Why is that not the one used to start the flake environment from direnv?

Edit: All good now that I applied previously mentioned fix with direnv.nix-direnv.enableFlakes = true; in home-manager conf and it worked. Didn't understand how direnv+nix-direnv got its nix package...
