Fixing the eventmachine Gem Installation Issue on Jekyll: Insights and Solutions

Setting up Jekyll on your local machine can be a frustrating experience, particularly when you encounter installation errors like the common eventmachine gem installation failure. Many developers face this issue, especially when working on environments with specific Ruby versions like Ubuntu 20.04. If you've tried bundle install and ended up staring at cryptic error messages, you're not alone. In this guide, we’ll address the problem and outline steps you can take to resolve it effectively.

The Problem: Understanding the eventmachine Error

The eventmachine gem is a crucial dependency for Jekyll and various plugins. When users run bundle install, they might encounter a Gem::Ext::BuildError indicating that the gem failed to build a native extension. This problem can stem from:

Incompatibility Issues: The Ruby version in use may have compatibility issues with the gem.

System Dependencies: Required system packages may be missing or incorrectly configured.

Missing Permissions or Tools: Sometimes, essential build tools like make and mkdir might not be correctly set up in the environment.

Typical Symptoms

When facing this issue, you might see messages like:

Error messages regarding make or mkdir commands not found.

Compilation errors related to .cpp files.

Confusing logs that give little insight into the underlying cause.

The Solution: Steps to Resolve the Issue

After extensive experimentation, a viable solution emerged that can help users bypass this installation hurdle. Here’s a structured approach to resolve the eventmachine installation error:

1. Change Ruby Version

One significant workaround discovered was switching the Ruby version from 2.7.2 to 2.7.1. This seemingly minor adjustment made a substantial difference in clearing the installation blockade. Here’s how to do it:

Use RVM (Ruby Version Manager) to change your Ruby version:
