environment.systemPackages = with pkgs; [
obs-studio # contoh meng-install obs-studio
];
Then, after adding the package name(s), run this command on the terminal:
sudo nixos-rebuild switch # directly switch to a new profile
sudo nixos-rebuild boot # apply the alteration on the boot menu
sudo nixos-rebuild test # try the change without saving it on the boot menu
home.nix:
home.packages = with pkgs; [
obs-studio
];
Then, after adding the package name(s), run this command on the terminal:

- Alternatively, install a package as a temporary one:
nix-shell -p obs-studio
- To remove package(s), simply remove it from the config files and run this command on the terminal:
# for configuration.nix
sudo nixos-rebuild switch # directly switch to a new profile
sudo nixos-rebuild boot # apply the alteration on the boot menu
sudo nixos-rebuild test # try the change without saving it on the boot menu
