Quick Start

# Install Ruby 3.3
rvm install 3.3

# Switch to it
rvm use 3.3

# Make it the default
rvm use 3.3 --default

# List installed rubies
rvm list

Core Command Tracks

  • Install Ruby: rvm install 3.3 / rvm install ruby-3.3.0
  • Switch version: rvm use 3.3
  • Set default: rvm use 3.3 --default
  • List rubies: rvm list / rvm list known
  • Gemsets: rvm gemset create myapp, rvm gemset use myapp
  • Current ruby: rvm current
  • Remove ruby: rvm uninstall 3.1

Safety Guardrails

  • Import the GPG key before installing rvm to verify the installer signature.
  • Always run rvm as a login shell function — do not invoke it as a plain command in non-login sub-shells.
  • Commit .ruby-version (not .rvmrc) to version control; .rvmrc requires rvm rvmrc trust per machine.
  • Use project-specific gemsets to isolate gem dependencies and avoid version conflicts between projects.

Workflow

  1. Install the target Ruby version with rvm install <version>.
  2. Create a project gemset: rvm gemset create <name>.
  3. Switch to version + gemset: rvm use <version>@<name>.
  4. Write .ruby-version and .ruby-gemset (or use rvm --create --ruby-version use) to autoswitch.
  5. Run bundle install to install project gems into the active gemset.
# Troubleshoot: rvm not found in a sub-shell, source the shell function manually
source "$HOME/.rvm/scripts/rvm"
rvm current
rvm list
