Getting error "does not provide attribute" when following your book

[Le Tien Dat]

I'm trying go through your tutorial about enabling Flakes in NixOS, and unfortunately, i get this error when try to run command : sudo nixos-rebuild switch

Error details:

error: flake 'path:/etc/nixos' does not provide attribute 'packages.x86_64-linux.nixosConfigurations."nixos".config.system.build.nixos-rebuild', 'legacyPackages.x86_64-linux.nixosConfigurations."nixos".config.system.build.nixos-rebuild' or 'nixosConfigurations."nixos".config.system.build.nixos-rebuild'

I'm not trying to change anything beyond your instructions to avoid errors, what am I missing?

So do you have /etc/nixos/configuration.nix and /etc/nixos/flake.nix on your NixOS host, and what're their contents?

[Le Tien Dat]

I just figure out the solution based on your comment, instead run sudo nixos-rebuild switch, i have to run sudo nixos-rebuild switch --flake /etc/nixos#nixos-test

[Ryan Yin]

Oh got it, your hostname isn't nixos-test, I overlooked that.

Fixed, thanks for your feedback!
