Creating a New Rails App

We’re going to build a project called store - a simple e-commerce app that demonstrates several of Rails’ built-in features.

Prerequisites

For this project, you will need Ruby 3.2 or newer, Rails 8.0.0 or newer, a code editor… nothing! Everything you need to build your first Rails application is already “installed” in your browser.

Let’s verify the correct version of Rails is installed. To display the current version, go to the terminal and run the following. You should see a version number printed out:

$ rails --version
Rails 8.0.2

The version shown should be Rails 8.0.0 or higher.
