[2 min installs] Ruby on Rails on Ubuntu

Here is how to install Ruby on Rail in under two minutes:

Step 1 - Install dependencies

Before installing Ruby on Rails, you need to install its dependencies first.

1. Update package list on your system:

sudo apt-get update -y

1. Install build-essentials

sudo apt-get install build-essential

1. Install the developer dependencies.

sudo apt-get install libssl-dev zlib1g-dev sqlite3 libsqlite3-dev

1. Install Git and curl if not already installed.

sudo apt-get install git curl

Step 2 - Install Nodejs & Yarn

Rails use the JavaScript runtime through Node.js to build the applications.

1. Install the latest Node.js version (if not already installed)

curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
sudo apt-get install nodejs

1. Install Yarn

curl -fsSL https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update && sudo apt-get install yarn

Step 3 - Install rbenv

rbenv is a Ruby version manager used to install and manage Ruby environments.

1. Install rbenv

curl -fsSL https://github.com/rbenv/rbenv-installer/raw/HEAD/bin/rbenv-installer | bash

1. Add rbenv to the path

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

Step 4 - Install Ruby

Now it is time to install the latest stable version of Ruby language. If you have done this already, you can skip this step.

1. List the latest Ruby versions

rbenv install -l

1. Install the desired version (rails require version 2.5.0 or newer)

rbenv install 3.0.2 -v

1. Set global Ruby version

rbenv global 3.0.2

1. Install ruby bundler using gem

gem install bundler

Step 5 - Install Rails

Finally, install rails using the following command:

gem install rails

That’s it

You have installed Ruby on Rails on your system. To test if everything worked, create a test project and run it:

rails new hello-world
cd hello-world
rails server --binding=0.0.0.0
