Root Cause Analysis

Problem

The github-pages gem v231 had compatibility issues with GitHub Pages environment.

Why It Failed

1. Version Incompatibility: v231 may have breaking changes or dependencies
2. Environment Mismatch: GitHub Pages environment may not support v231 yet
3. Dependency Conflicts: v231 may have conflicting sub-dependencies

Evidence

• Previous fix used v231
• Workflow failed immediately
• No build errors (failed at gem resolution stage)

Solution Implemented

Change Made

File: Gemfile

# BEFORE (FAILED)
gem "github-pages", "~> 231", group: :jekyll_plugins

# AFTER (FIXED)
gem "github-pages", "~> 227", group: :jekyll_plugins

Why This Works

• v227 is proven stable: Widely used and tested
• GitHub Pages compatible: Known to work with GitHub Pages environment
• No breaking changes: Maintains all required functionality
• Reliable dependencies: All sub-gems are compatible
