1. **Install nvm:** First, ensure that `nvm` is installed. To install `nvm` on Linux or macOS, run the following command:

```sh
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
```

Alternatively, if you are using Windows, you can use `nvm-windows`:

```sh
nvm install-latest-npm
```

2. **List Available Node.js Versions:** Once `nvm` is installed, you can view all available Node.js versions:

```sh
nvm ls-remote
```

3. **Install Node.js:** Use `nvm` to install a specific version of Node.js. `npm` will be bundled with this version:

```sh
nvm install 14.17.0
```

This will install Node.js 14.17.0 and the compatible `npm` version.

4. **Switch Node.js Version:** After installing multiple versions of Node.js, you can switch between them using the following command:

```sh
nvm use 14.17.0
```

This will switch to Node.js 14.17.0 and the corresponding `npm` version.

5. **Upgrade npm:** If you want to upgrade `npm` for the currently used Node.js version, run:

```sh
npm install -g npm@latest
```

This will install the latest version of `npm` for the currently selected Node.js version.

6. **Check npm Version:** You can verify the `npm` version by running the following command:

```sh
npm --version
```

7. **Install Specific npm Version for a Node.js Version:** If you need to install a specific version of `npm` for a specific Node.js version, first switch to that Node.js version, then install the specified `npm` version:

```sh
nvm use 14.17.0
npm install -g npm@6.14.13
```

This will install `npm` 6.14.13 for Node.js 14.17.0.

The following are the basic steps to manage and change `npm` versions using `nvm`. This simplifies switching development environments across different projects, as each project may require different Node.js and `npm` versions.
