Which Ruby version managers does this skill support?

It supports a wide range of managers including shadowenv, chruby, rbenv, rvm, asdf, rv, and mise.

How do I handle multiple version managers on the same machine?

The skill includes a preference management system that allows you to select and save a preferred manager via the set-preference.sh script.

Why is a version manager skill necessary for Claude Code?

Claude Code executes each command in a fresh shell instance, meaning standard environment modifications (like switching Ruby versions) don't persist. This skill provides the activation commands to chain with your Ruby tasks.

Does it work with Ruby versions specified in a Gemfile?

Yes, it parses Gemfiles as well as .ruby-version and .tool-versions files to determine the correct environment requirements.

What happens if the required Ruby version isn't installed?

The skill will identify the missing version and provide the specific installation command for your detected manager, asking for your permission before proceeding.

Detects and configures Ruby version managers to ensure consistent development environments across Claude Code sessions.

소개

The Ruby Version Manager skill automates the setup of your Ruby development environment by identifying project-specific configuration files like .ruby-version, Gemfile, or .tool-versions. It specifically addresses the challenge of non-persistent shell sessions in Claude Code by generating the exact activation commands needed for managers like rbenv, RVM, chruby, and asdf. By proactively detecting the environment before running Ruby commands, it prevents version mismatch errors and streamlines the workflow for Rails, RSpec, and general Ruby development.
