@ -32,7 +32,7 @@ The following are classic Nix commands and associated concepts that are no longe
1. In Flakes, the functionality of `nix-channel` is entirely replaced by the `inputs` section in `flake.nix`.
2. `nix-env`: `nix-env` is a core command-line tool for classic Nix used to manage software packages in the user environment.
1. It installs packages from the data sources added by `nix-channel`, causing the installed package's version to be influenced by the channel. Packages installed with `nix-env` are not automatically recorded in Nix's declarative configuration and are completely independent of its control, making them challenging to reproduce on other machines. Therefore, it is not recommended to use this tool.
2. The corresponding command in Flakes is `nix profile`. Personally, I don't recommend it either.
2. The corresponding command in Flakes is `nix profile`. Personally, I don't recommend it for beginners either.
3. `nix-shell`: `nix-shell` creates a temporary shell environment, which is useful for development and testing.
1. In Flakes, this tool is divided into three sub-commands: `nix develop`, `nix shell`, and `nix run`. We will discuss these three commands in detail in the "[Development](../development/intro.md)" chapter.
4. `nix-build`: `nix-build` builds Nix packages and places the build results in `/nix/store`, but it does not record them in Nix's declarative configuration.

@ -38,7 +38,7 @@ Nix 于 2020 年推出了 `nix-command` & `flakes` 两个新特性，它们提
1. Nix Flakes 在 `flake.nix` 中通过 `inputs` 声明依赖包的数据源，通过 `flake.lock` 锁定依赖版本，完全取代掉了 `nix-channel` 的功能。
2. `nix-env`: 用于管理用户环境的软件包，是传统 Nix 的核心命令行工具。它从 `nix-channel` 定义的数据源中安装软件包，所以安装的软件包版本受 channel 影响。
1. 通过 `nix-env` 安装的包不会被自动记录到 Nix 的声明式配置中，是完全脱离掌控的，无法在其他主机上复现，因此不推荐使用。
2. 在 Nix Flakes 中对应的命令为 `nix profile`，我个人也不太推荐直接使用它.
2. 在 Nix Flakes 中对应的命令为 `nix profile`，我个人也不太推荐初学者尝试它.
3. `nix-shell`: nix-shell 用于创建一个临时的 shell 环境
1. 这玩意儿可能有点复杂了，因此在 Nix Flakes 中它被拆分成了三个子命令 `nix develop`, `nix shell` 以及 `nix run`，我们会在「[构建开发环境](../development/intro.md)」一章详细介绍这三个命令。
4. `nix-build`: 用于构建 Nix 包，它会将构建结果放到 `/nix/store` 路径下，但是不会记录到 Nix 的声明式配置中。
