Step 1: Installing Ruby

To install Ruby and Rails on Ubuntu, you’ll need  to install some dependencies. To make that happen, install Node.js and Yarn repositories. This will make installing the dependencies easier.

curl -sL  | sudo -E bash -
curl -sS  | sudo apt-key add -
echo "deb  stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

sudo apt-get update
sudo apt-get install nodejs yarn zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common libffi-dev

When you’re done. continue below:

After adding the repositories and installing necessary packages above, install Ruby with your local profile settings using rbenv. you’ll then use rbenv to install ruby-build.

cd ~/
git clone  ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone  ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
