作者介绍了 [Nix: the package manager](https://nixos.org/)。

> Nix is a tool that takes a unique approach to package management and system configuration. Learn how to make reproducible, declarative and reliable systems.

​## 环境配置（Archlinux）

安装：

```bash

sudo pacman -S nix nix-channel –add https://nixos.org/channels/nixpkgs-unstable nix-channel –update nix-env -u source /etc/profile.d/nix{,-daemon}.sh sudo systemctl enable nix-daemon.service sudo usermod -aG nix-users archie ```

If you installed Nix from the official repositories, you must add the `~/.nix-profile/bin` directory to your PATH manually.

卸载：

```bash sudo pacman -Rs nix rm -r ~/.nix-channels ~/.nix-defexpr ~/.nix-profile sudo rm -r /nix

```
