Summary

RVM is a command-line tool for installing and managing multiple Ruby environments, from interpreters to gem sets. It can create a self-contained environment for each project with a selected Ruby version and its required gems. Named gemsets help manage gems across Ruby versions, and a shared cache keeps one on-disk copy of each downloaded gem. RVM can run test suites, rake tasks, benchmarks and gem commands against multiple Ruby versions. Its documented integrations include Bundler, Capistrano, Chef, Jenkins, Heroku and Passenger. Commands cover installing, selecting, upgrading, reinstalling, uninstalling and removing Ruby versions. RVM supports most UNIX-like systems and Windows through Cygwin or Bash on Ubuntu on Windows. Basic installation requires Bash, curl, gpg2 and GNU tools; git is needed to install head Ruby versions. It documents single-user, multi-user and mixed-mode setups, and recommends single-user installation for an isolated home-directory environment. RVM says it signs releases and the installer with GPG and verifies signatures during updates. Community volunteers maintain the project, with support through issue trackers and pull requests.

Who it is for

RVM suits Ruby developers who need separate project environments or need to run commands across multiple Ruby versions. It also fits teams seeking consistent Ruby environments across development, CI, QA, staging and production.

What is good

Creates isolated environments for projects.
Runs tests and commands against multiple Ruby versions.
Named gemsets organize gems across versions.
Supports common Ruby ecosystem integrations.
Release and installer signatures are verified.

What to know first

Installation requires Bash, curl, gpg2 and GNU tools.
Git is required to install head Ruby versions.
Windows support is through Cygwin or Bash on Ubuntu on Windows.
Community volunteers provide support through issue trackers and pull requests.

Verdict

RVM brings Ruby versions, gemsets and project environments under command-line management. It is a fit for Ruby workflows that need isolation or multi-version testing, provided the installation requirements suit your system.
