error: failed to parse lock file at: /build/dummy-src/Cargo.lock

[dvaerum]

I am getting this error when I try to build my flake package in NixOS, but if I try to build the package using nix build it works perfectly fine. Has anyone seen this before? cause I don't seem to find anything about it when searching.

Link to package: https://github.com/dvaerum/gpg-ssh

[i-am-logger]

i'm getting this now in a flake.nix file

were you able to resolve it?

from what i see it uses the stable rather then nightly and am not sure why

[i-am-logger]

i had to change mine from
nixpkgs.url = "github:cachix/devenv-nixpkgs/rolling";
to
nixpkgs-unstable.url = "github:nixos/nixpkgs/nixos-unstable";

[dvaerum]

Nope, I have not found a solution yet, but I will give yours a try, when I get back to playing with it

[i-am-logger]

don't forget the follows

nixpkgs-unstable.url = "github:nixos/nixpkgs/nixos-unstable";
systems.url = "github:nix-systems/default";
fenix.url = "github:nix-community/fenix";
fenix.inputs.nixpkgs.follows = "nixpkgs";
naersk.url = "github:nix-community/naersk";
naersk.inputs.nixpkgs.follows = "nixpkgs";

[i-am-logger]

anf if you use devenv

devenv.url = "github:cachix/devenv";
devenv.inputs.nixpkgs.follows = "nixpkgs";
