Install Nix via the recommended [multi-user installation]:

|
|
|
|
2022-11-08 11:37:41 -05:00
|
|
|
```shell-session
|
|
|
|
|
$ sh <(curl -L https://nixos.org/nix/install) --daemon
|
2021-12-10 09:48:34 -05:00

## Windows (WSL2)
|
|
|
|
|
|
2022-12-04 03:16:32 -05:00
|
|
|
Install Nix via the recommended [single-user installation]:
|
2021-12-10 09:48:34 -05:00
|
|
|
|
2022-11-08 11:37:41 -05:00

|
```shell-session
|
|
|
|
|
$ sh <(curl -L https://nixos.org/nix/install) --no-daemon
|
2021-12-10 09:48:34 -05:00

|
```
|

However, if you have [systemd support] enabled, install Nix via the recommended [multi-user installation]:
|
|
|
|
|
|
|
|
|
|
```shell-session
|
|
|
|
|
$ sh <(curl -L https://nixos.org/nix/install) --daemon
|
|

## Docker
|
|
|
|
|
|
|
|
|
|
Start a Docker shell with Nix:
|
|
|
|
|
|
2022-11-08 11:37:41 -05:00
|
|
|
```shell-session
|
2021-12-10 09:48:34 -05:00
|
|
|
$ docker run -it nixos/nix
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Or start a Docker shell with Nix exposing a `workdir` directory:
|
|
|
|
|
|
2022-11-08 11:37:41 -05:00
|
|
|
```shell-session
|
2021-12-10 09:48:34 -05:00
|
|
|
$ mkdir workdir
|
|
|
|
|
$ docker run -it -v $(pwd)/workdir:/workdir nixos/nix
|
|
|
|
|
```
|
|
|
|
|
|
2022-09-26 07:19:18 -04:00
|
|
|
The `workdir` example from above can be also used to start hacking on Nixpkgs:
|
2021-12-10 09:48:34 -05:00
|
|
|
|
2022-11-08 11:37:41 -05:00
|
|
|
```shell-session
|
2021-12-10 09:48:34 -05:00
|
|
|
$ git clone git@github.com:NixOS/nixpkgs
|
|
|
|
|
$ docker run -it -v $(pwd)/nixpkgs:/nixpkgs nixos/nix
|
2022-11-08 11:37:41 -05:00
|
|
|
bash-5.1# nix-build -I nixpkgs=/nixpkgs -A hello
|
|
|
|
|
bash-5.1# find ./result # this symlink points to the build package
|
2021-12-10 09:48:34 -05:00
|
|
|
```
|
|
|
|
|
|
|
|
|
|
