First of all, it does not ask you to install Node.js runtime OR npm package manager, it offers you to install them both (if you want)
首先，它不会要求您安装 Node.js 运行时或 npm 包管理器，它会提供您安装它们（如果需要）
Now, Node.js runtime is basically what will understand your javascript code and execute it to produce a result.
现在，Node.js 运行时基本上可以理解您的 javascript 代码并执行它以产生结果。
Npm package manager is a tool which will allow you to install third party libraries (other people's code) by using the command line.
Npm 包管理器是一个工具，它允许您使用命令行安装第三方库（其他人的代码）。
npm install express
will install the framework called express for example.
例如，将安装名为 express 的框架。

- Node and Nodejs are the same. Interchangeable names for the same thing. Unless someone is talking about graph theory, trees or data structures.
- Nvm is a Nodejs version manager. It let's you easily install and switch between versions. It retains globally installed packages for each version.
- Npm is a package manager. It let's you install software (libraries, plugins, frameworks and applications). Typically this software is installed to build Node applications. Sometimes it isn't.
- Node 和 Nodejs 是一样的。同一事物的可互换名称。除非有人在谈论图论、树或数据结构。
- Nvm 是一个 Nodejs 版本管理器。它让您轻松安装和在版本之间切换。它为每个版本保留全局安装的包。
- Npm 是一个包管理器。它让您安装软件（库、插件、框架和应用程序）。通常安装此软件来构建 Node 应用程序。有时不是。
Put more simply. Npm depends on Node. Nvm installs Node.
说得简单点。Npm 依赖于 Node。Nvm 安装节点。

You can differentiate them by finding their version using below code.
您可以通过使用以下代码查找它们的版本来区分它们。
node --version
npm --version
