SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Migrating from rbenv to mise by reading existing .ruby-version files, handling rbenv-gemset, and cleanly tearing down ~/.rbenv so you can adopt mise for Ruby version management.

Core Features & Use Cases

  • Inventory and assess rbenv state across projects (installed rubies, current version, global pin).
  • Generate per-project mise.toml mappings and enable idiomatic readers for .ruby-version and Gemfile pins.
  • Swap shell RC configurations and verify rubies map to project pins; uninstall rbenv safely.

Quick Start

Follow the migration plan to switch from rbenv to mise in your shell and project configurations.

FAQPage Schema
How do I migrate from rbenv to mise while keeping my Ruby version pins?▼

To migrate from rbenv to mise, the process reads existing .ruby-version files and reconfigures tooling to generate a per-project mise.toml, ensuring your Ruby version pins remain intact across local development and CI.

What is the best way to handle rbenv-gemset when switching to mise?▼

When switching to mise, existing rbenv-gemset configurations are inventoried and mapped into per-project mise.toml files, allowing idiomatic readers to manage Gemfile pins and replace gemset dependencies.

How do I safely uninstall rbenv after switching to mise?▼

Safely uninstalling rbenv involves generating per-project mise.toml mappings, swapping shell RC configurations, verifying rubies map to project pins, and cleanly tearing down ~/.rbenv only after validation.

Does migrating to mise require updating my shell rc and bundler config?▼

Yes, migrating to mise requires swapping shell RC configurations to point to mise, alongside adjusting bundler and project config settings to enable idiomatic readers for .ruby-version and Gemfile pins.

Can I use mise for Ruby version management in CI environments previously using rbenv?▼

Yes, mise applies Ruby version management to CI environments by reading existing project pins and reconfiguring tooling, replacing rbenv-gemset dependencies with a unified mise.toml configuration.
