Final answer:
To update Node version in npm, check your current version with 'node -v', and then either download the latest version from the Node.js website or use a version manager like nvm or n. Installation with nvm can be done using 'nvm install version_number' and 'nvm use version_number'. Note that updating Node.js also updates npm since it comes bundled with Node.js.
Step-by-step explanation:
The process for updating the Node version in npm (Node Package Manager) involves a few steps. First, you should check your current version of Node.js with the command node -v in your terminal. If you find that your Node version is outdated and want to update it, the most straightforward method is to download the latest version from the official Node.js website.
If you prefer to update Node.js via your terminal, you could use a version management tool like nvm (Node Version Manager) or n to install new versions of Node.js and switch between them. For example, using nvm, you can install a specific version of Node.js with the command nvm install version_number, and then use it by running nvm use version_number.
It's important to note that npm does not control Node.js versions, it is bundled with Node.js, so you update it as you update Node.js itself. After updating Node.js, npm will generally be updated as well because each new Node.js version comes with a specific version of npm.
