Install Ruby Using Ruby Version Manager (RVM)

Installation

Install GPG Keys:

gpg2 --keyserver keyserver.ubuntu.com --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

Install RVM:

curl -sSL https://get.rvm.io | bash -s stable

Use the following to your shell config so RVM is usable:

echo '[ -f "$HOME/.rvm/scripts" ] && . "$HOME/.rvm/scripts/rvm"' >> ~/.bashrc

List all available versions:

rvm list known

Install a specified version:

rvm install ruby 3.3.0

List installed versions:

rvm list

Set the default Ruby:

rvm --default use ruby-3.3.0

Revert to using the system default:

rvm use system

or:

rvm reset

Troubleshooting

Error running __rvm_make

Try to update your rvm with head and try again, hopefully it should fix this:

rvm get head

Cannot load such file – openssl

rvm pkg install openssl

Reinstall your version with the new openssls:

rvm reinstall ruby-3.3.0 --with-openssl-dir="$rvm_path/usr"

or reinstall all versions:

rvm reinstall all --force
