Cannot run devenv gc

[p16i]

Describe the bug
I have just moved to nixOS, and I am learning how to use devenv for my development environments. It seems that the devenv gc due to an error of unexpected argument for the command nix store gc.

To reproduce

In this case, the devenv.nix and devenv.yaml that I have are directly from what devenv init provides.

I'm experiencing siimilar error with devenv gc and devenv 1.0.4 caused by the unknown impure argument:

@p16i does /nix/store/wymhs667k4ggiaz7lq1vcycsi97vkmwf-devenv-shell-env exist?

[p16i]

@domenkozar thanks for promptly response!

This is what I got

$ ls -la  /nix/store/wymhs667k4ggiaz7lq1vcycsi97vkmwf-devenv-shell-env
-r--r--r-- 1 root root 71596 Jan  1  1970 /nix/store/wymhs667k4ggiaz7lq1vcycsi97vkmwf-devenv-shell-env

It is there but empty.

@domenkozar thanks for working on the issue 🙌

Btw is there a way how to run gc manually? I've tried to remove impure: true from my devenv.yaml, but it's still failing and I've already ran out of the disk space, completely blocked from using devenv rn.

sudo -E nix-collect-garbage

[sbocinec]

sudo -E nix-collect-garbage

Awesome, TY!

One OT note for others: the command didn't work with -E ( I have devenv & nix installed on Ubuntu 22.04):

$ sudo -E nix-collect-garbage
sudo: nix-collect-garbage: command not found

Though switching to root without preserving the env vars (sudo -i) and executing nix-collect-garbage worked:

stano@rpu ~/workspace/redpanda/cloudv2/apps/external-dns-helper (main*?) $ sudo -i
root@rpu:~# which nix-collect-garbage 
/root/.nix-profile/bin/nix-collect-garbage
root@rpu:~# 
logout

$ which nix-collect-garbage
/nix/var/nix/profiles/default/bin/nix-collect-garbage
