This guide describes how to install Ruby on Rails on Debian 11.
We will do everything through the console in a few steps.

First, we install the necessary packages:

apt-get install gnupg2 curl wget -y

We add the key to the system:

gpg2 --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
curl -sSL https://rvm.io/pkuczynski.asc | gpg2 --import -

We download the RVM script

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

We link in the system:

source /usr/local/rvm/scripts/rvm

We can check the RVM version by issuing the command:

rvm version

the result of the:

rvm 1.29.12 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

We update rvm to the latest version by issuing a command:

rvm get stable --autolibs=enable

We give permission

usermod -a -G rvm root

We install Ruby:

rvm install ruby-3.0.2

We set the default version:

rvm --default use ruby-3.0.2

Installation of Nodejs and Yarn

We install the necessary packages:

apt-get install gcc g++ make -y

We download the script:

curl -sL https://deb.nodesource.com/setup_14.x | bash -

We add a Yarn repo to the system:

curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list

We install nodejs and yarn:

apt-get update

apt-get install nodejs yarn -y

We are updating Gem packages:

gem update --system

The last step is to install rails with the command:

gem install rails -v 6.1.4
