### Prerequisites {#sec-flakes-prerequisites}
|
||
|
|
|
||
|
|
To install nvf with flakes, you must make sure the following requirements are
|
||
|
|
met.
|
||
|
|
|
||
|
|
1. Nix 2.4 or later must be installed. You may use `nix-shell` to get a later
|
||
|
|
version of Nix from nixpkgs.
|
||
|
|
2. Flake-related experimental features must be enabled. Namely, you need
|
||
|
|
`nix-command` and `flakes`. Some Nix vendors enable those by default, please
|
||
|
|
consult their documentation if you are not using mainstream Nix.
|
||
|
|
- When using NixOS, add the following to your `configuration.nix` and rebuild
|
||
|
|
your system.
|
||
|
|
|
||
|
|
```nix
|
||
|
|
nix.settings.experimental-features = "nix-command flakes";
|
||
|
|
```
|
||
|
|
|
||
|
|
- If you are not using NixOS, add the following to `nix.conf` (located at
|
||
|
|
`~/.config/nix/` or `/etc/nix/nix.conf`).
|
||
|
|
|
||
|
|
```bash
|
||
|
|
experimental-features = nix-command flakes
|
||
|
|
```
|
||
|
|
|
||
|
|
- You may need to restart the Nix daemon with, for example,
|
||
|
|
`sudo systemctl restart nix-daemon.service`.
|
||
|
|
|
||
|
|
- Alternatively, you can enable flakes on a per-command basis with the
|
||
|
|
following additional flags to `nix` and `home-manager`:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ nix --extra-experimental-features "nix-command flakes" <sub-commands>
|
||
|
|
```
