Verification & Installation of System Runtimes

Before diving into theme engineering, you must ensure your local development machine has the required system runtimes installed. WP Rig relies on modern compiler libraries and package managers to achieve fast, optimized asset builds and static PHP analysis.

In this lesson, you will learn how to verify and install the core dependencies of WP Rig v3.

The Required Runtimes

Ensure your terminal can access the following five system packages:

1. Git (Source Control)

2. Node.js (v20+ or newer)

3. Bun (High-Performance Runtime)

4. PHP (v8.1 or higher – v8.3 Recommended)

5. Composer (PHP Dependency Manager)

Summary Checklist

Run this command in your terminal to verify that everything is configured correctly:

git --version && node --version && bun --version && php --version && composer --version

If all commands output successful version strings, your development machine is fully primed! In the next lesson, we will set up your local WordPress development site.
