Ruby Managers and Installers

If you have installed GraalVM, it is recommended to add TruffleRuby to a Ruby manager. See Configuring Ruby managers for the full GraalVM distribution below.

Installing TruffleRuby with RVM, ruby-build or ruby-install

TruffleRuby is supported by the 3 major Ruby installers.

RVM

Upgrade RVM to let RVM know about the latest TruffleRuby release:

rvm get head

Install the latest TruffleRuby release with:

rvm install truffleruby

You can also install the latest nightly build of TruffleRuby with:

rvm install truffleruby-head

ruby-build and rbenv

We assume you already have ruby-build installed as a plugin for rbenv.

First, you need to upgrade ruby-build to get the latest TruffleRuby definition. See ruby-build's instructions for upgrading.

On macOS, if ruby-build is installed via Homebrew and you do not see the latest TruffleRuby release, you might need to install the HEAD version of ruby-build with:

brew reinstall --HEAD ruby-build

Check the latest available version of TruffleRuby with:

rbenv install --list | grep truffleruby

Then install the latest TruffleRuby release with:

rbenv install truffleruby-[LATEST_VERSION]

You can also install the latest nightly build of TruffleRuby with:

rbenv install truffleruby-dev

ruby-install and chruby

First, you need at least ruby-install 0.7.1 to get TruffleRuby support. Check your version with:

ruby-install --version

If it is older than 0.7.1, you need to update to latest ruby-install. Follow the installation instructions, since the steps for upgrading ruby-install are the same as the steps for installing it.

Then install the latest TruffleRuby release with:

ruby-install --latest
ruby-install truffleruby

ruby-install does not support installing nightly builds. Please use ruby-build (which also works with chruby) if you want to install nightly builds:

ruby-build truffleruby-dev ~/.rubies/truffleruby-dev

There are also instructions on the chruby wiki if you prefer to install TruffleRuby manually.

Configuring Ruby Managers for the Full GraalVM Distribution

When installing GraalVM and Ruby, it is recommended to add TruffleRuby to a Ruby manager for ease of use.

Make sure you ran the post-install script before adding GraalVM to Ruby managers.

Then follow these steps to integrate GraalVM with your Ruby manager.

The first step is to find the TruffleRuby home. On macOS, run:

ruby_home=$(path/to/graalvm/Contents/Home/bin/ruby -e 'print RbConfig::CONFIG["prefix"]')

On Linux and other platforms, run:

ruby_home=$(path/to/graalvm/bin/ruby -e 'print RbConfig::CONFIG["prefix"]')

rbenv

To add TruffleRuby to rbenv, create a symbolic link in the versions directory of rbenv:

ln -s "$ruby_home" "$RBENV_ROOT/versions/truffleruby"
rbenv shell truffleruby
ruby --version

chruby

To add TruffleRuby to chruby, create a symbolic link to the $HOME/.rubies directory:

ln -s "$ruby_home" "$HOME/.rubies/truffleruby"
chruby truffleruby
ruby --version

RVM

RVM has a command for adding a precompiled Ruby to the list of available rubies.

rvm mount "$ruby_home" -n truffleruby
rvm use ext-truffleruby
ruby --version

asdf (with asdf-ruby plugin)

Adding Truffleruby to asdf functions much like rbenv or chruby, create a symbolic link in the .installs/ruby directory but you also need to reshim:

ln -s "$ruby_home" "$HOME/.asdf/installs/ruby/truffleruby"
asdf reshim ruby truffleruby
asdf local ruby truffleruby
ruby --version

Using TruffleRuby without a Ruby Manager

If you are using a Ruby manager like rvm, rbenv, or chruby and wish not to add TruffleRuby to one of them make sure that the manager does not set environment variables GEM_HOME and GEM_PATH. The variables are picked up by TruffleRuby (as any other Ruby implementation would do) causing TruffleRuby to pickup the wrong Gem home instead of its own.

It can be fixed for the current terminal by clearing the environment with one of the following commands:

rbenv system
chruby system
rvm use system
# Or manually:
unset GEM_HOME GEM_PATH
You can’t perform that action at this time.
