Easily Upgrade Node.js to the Latest LTS Version on macOS Without Brew

Learn how to upgrade any version of Node.js to the latest LTS release on macOS without using Homebrew or other tools. Follow these simple terminal commands for a smooth update.

Introduction

Keeping your Node.js environment up-to-date is crucial for leveraging new features, improved performance, and enhanced security. If you’re a macOS user looking to upgrade Node.js to the latest Long Term Support (LTS) version without installing additional tools like Homebrew, you’re in the right place. This guide will walk you through the process using straightforward terminal commands, utilizing npm and the n version manager.

Why Upgrade to the Latest LTS Version?

Upgrading to the latest LTS version of Node.js ensures maximum stability and support for your applications. LTS versions are maintained for an extended period, receiving critical bug fixes and security updates. This makes them ideal for production environments where reliability is paramount.

Prerequisites

• macOS System: This guide is specifically tailored for macOS users.
• npm Installed: Ensure you have npm (Node Package Manager) installed on your system.
• Administrative Privileges: You’ll need sudo access to execute certain commands.

Step-by-Step Upgrade Guide

Follow these steps in your macOS Terminal to upgrade Node.js to the latest LTS version without relying on external dependencies like Homebrew.

1. Clear the npm Cache

Clearing the npm cache helps prevent any conflicts or issues during the upgrade process.

sudo npm cache clean -f

• The -f flag forces the cache clean operation.
• Note: You may be prompted to enter your macOS user password due to the sudo command.

2. Install ‘n’ Globally

The n package is a Node.js version manager that simplifies the process of installing and switching between Node.js versions.

sudo npm install -g n

• This command installs n globally on your system.
• Note: The installation process might take a few minutes.

3. Upgrade to the Latest LTS Version

Now, use n to install the latest LTS version of Node.js.

sudo n stable

• Explanation: This command upgrades Node.js to the most recent Long Term Support version.
• Alternate Options:
• To upgrade to the latest version (which may include the newest features but might not be as stable), use:
  bash sudo n latest
• To upgrade to the current stable LTS version:
  bash sudo n lts
• To install a specific version (e.g., v16.13.0):
  bash sudo n 16.13.0

4. Verify the Installation

Check if Node.js has been upgraded successfully by checking the version.

node -v

• This command displays the installed Node.js version.
• Troubleshooting: If the version hasn’t updated, you might need to restart your terminal or reboot your system.

Additional Tips

• Restart Your Terminal or System: Sometimes, changes don’t take effect until after a terminal restart or system reboot.
• Update npm (Optional): After upgrading Node.js, consider updating npm to the latest version:

  sudo npm install -g npm

• Switch Between Versions: With n, you can easily switch between different Node.js versions installed on your system:

  sudo n

• This will present a menu of installed versions to choose from.

Conclusion

Upgrading Node.js to the latest LTS version on macOS is straightforward and doesn’t require additional tools like Homebrew. By following these simple steps, you ensure that your development environment is up-to-date, secure, and compatible with the latest packages and frameworks.

By maintaining an updated Node.js environment on your macOS system, you not only improve security and performance but also ensure compatibility with modern libraries and tools. Keep your development workflow smooth and efficient—happy coding!
