rv, the Ruby swiss army knife

Welcome to rv, a new Ruby version manager with high ambitions.

Today, you can install Ruby in one second flat.

Eventually, you'll be able to manage all your Rubies, tools, gems, and packages, faster than you would believe is possible.

Requirements

• Operating Systems: macOS 14 and up, Ubuntu 24.04 and up
• Ruby Versions: Ruby 3.4.1 and up
• Shells: zsh

Quickstart

brew install spinel-coop/tap/rv
echo 'eval "$(rv shell init zsh)"' >> ~/.zshrc
eval "$(rv shell init zsh)"

Usage

echo "3.4.5" > .ruby-version
time rv ruby install 3.4.5

Brought to you by Spinel

Spinel.coop is a collective of Ruby open source maintainers building next-generation developer tooling, like rv, and offering flat-rate, unlimited access to maintainers who come from the core teams of Rails, Hotwire, Bundler, RubyGems, rbenv, and more.

Future plans

All-in-one tooling for Ruby developers.

• Manage Ruby versions, gems, applications, tools, and scripts, effortlessly.
• Get rid of rvm, rbenv, chruby, asdf, mise, ruby-build, ruby-install, bundler, and rubygems, all at once.
• Install Ruby and all your gems in seconds, without having to compile anything ever again.

Future features

• Run any gem command instantly, like rvx rails new.
• Run any script, installing all needed gems, like rv run script.rb.
• Install gem CLIs with any needed rubies with rv tool install.
• Install precompiled Ruby versions in seconds with rv ruby install.
• Manage project gems with rv install, rv add, and rv remove.
• Create gems with rv gem, and publish them with rv publish.
