How to create a new Rails app running Rails 7.1 beta or main branch

Here is how to create a new Rails app that runs on Rails 7.1 beta1

gem install -v 7.1.0.beta1 rails

rails _7.1.0.beta1_ new myrails71app

Replace myrails71app with your own app name and you are good to go.

This will generate a Gemfile that has something like this inside and then install required gems for Rails 7.1.0.beta1

# Gemfile

gem "rails", "~> 7.1.0.beta1"

Here is how to create a new Rails app that runs on Rails main branch from GitHub:

rails new myrailsapp --main

This will generate a Gemfile that has something like this inside:

gem "rails", github: "rails/rails", branch: "main"

May you have a lot of ideas to try!
