Install Ruby and Bundler

Ruby 2.7 or newer is required.

Option 1: Install from packages

Alma/CentOS/Red Hat/Rocky

Version 7 of these distributions does not provide a new enough Ruby version. Use RVM to install Ruby 2.7 or newer.

Version 8 of these distributions provides Ruby 2.7. You can install it by running:

# dnf module enable ruby:2.7
# dnf install --enablerepo=devel ruby ruby-devel

Debian and Ubuntu

Debian 10 (buster) and Ubuntu 18.04 (bionic) ship with Ruby 2.5, which is too old for Arvados. Use RVM to install Ruby 2.7 or newer.

Debian 11 (bullseye) and Ubuntu 20.04 (focal) and later ship with Ruby 2.7 or newer, which is sufficient for Arvados.

# apt-get --no-install-recommends install ruby ruby-dev

Option 2: Install with RVM


We do not recommend using RVM unless the Ruby version provided by your OS distribution is older than 2.7.

Install gpg and curl

CentOS/Red Hat 7

yum install gpg curl which findutils procps

Alma/CentOS/Red Hat/Rocky 8+

dnf install gpg curl which findutils procps

Debian and Ubuntu

apt-get --no-install-recommends install gpg curl ca-certificates dirmngr procps

Install RVM, Ruby and Bundler

gpg --keyserver --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
\curl -sSL | bash -s stable --ruby=2.7.7

This command installs the Ruby 2.7.7 release, as well as the gem and bundle commands.

To use Ruby installed from RVM, load it in an open shell like this:

source /usr/local/rvm/scripts/rvm

Alternately you can use rvm-exec (the first parameter is the ruby version to use, or “default”), for example:

rvm-exec default ruby -v
