# How do I override the package used by a module? {#_how_do_i_override_the_package_used_by_a_module}
|
||
|
|
|
||
|
|
By default Home Manager will install the package provided by your chosen
|
||
|
|
`nixpkgs` channel but occasionally you might end up needing to change
|
||
|
|
this package. This can typically be done in two ways.
|
||
|
|
|
||
|
|
1. If the module provides a `package` option, such as
|
||
|
|
`programs.beets.package`, then this is the recommended way to
|
||
|
|
perform the override. For example,
|
||
|
|
|
||
|
|
``` nix
|
||
|
|
programs.beets.package = pkgs.beets.override { enableCheck = true; };
|
||
|
|
```
|
||
|
|
|
||
|
|
2. If no `package` option is available then you can typically override
|
||
|
|
the relevant package using an
|
||
|
|
[overlay](https://nixos.org/nixpkgs/manual/#chap-overlays).
|
||
|
|
|
||
|
|
For example, if you want to use the `programs.skim` module but use
|
||
|
|
the `skim` package from Nixpkgs unstable, then a configuration like
|
||
|
|
|
||
|
|
``` nix
|
||
|
|
{ pkgs, config, ... }:
|
||
|
|
|
||
|
|
let
|
||
|
|
|
||
|
|
pkgsUnstable = import <nixpkgs-unstable> {};
|
||
|
|
|
||
|
|
in
|
||
|
|
|
||
|
|
{
|
||
|
|
programs.skim.enable = true;
|
||
|
|
|
||
|
|
nixpkgs.overlays = [
|
||
|
|
(self: super: {
|
||
|
|
skim = pkgsUnstable.skim;
|
||
|
|
})
|
||
|
|
];
|
||
|
|
|
||
|
|
# …
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
should work OK.
