- nixpkgs:
- update pkg
- `nix-env -i pkg-name -f <path to your local nixpkgs folder>`
- `nix-env -iA pkg-attribute-name -f <path to your local nixpkgs folder>`
- add pkg
- Make sure it’s in `pkgs/top-level/all-packages.nix`
- `nix-env -i pkg-name -f <path to your local nixpkgs folder>`
- `nix-env -iA pkg-attribute-name -f <path to your local nixpkgs folder>`
- _If you don’t want to install pkg in you profile_.
- `nix-build -A pkg-attribute-name <path to your local nixpkgs folder>/default.nix` and check results in the folder `result`. It will appear in the same directory where you did `nix-build`.
- If you did `nix-env -i pkg-name` you can do `nix-env -e pkg-name` to uninstall it from your system.
- `nix-build -A pkg-attribute-name <path to your local nixpkgs folder>` and check results in the folder `result`. It will appear in the same directory where you did `nix-build`.
- If you installed your package with `nix-env`, you can run `nix-env -e pkg-name` where `pkg-name` is as reported by `nix-env -q` to uninstall it from your system.
- NixOS and its modules:
- You can add new module to your NixOS configuration file (usually it’s `/etc/nixos/configuration.nix`). And do `sudo nixos-rebuild test -I nixpkgs=<path to your local nixpkgs folder> --fast`.
