Introduction

Whenever I start a new rails project I try to use the latest versions available.
In this post I will try to explain what is necessary to create a new rails project with the latest versions available.

Requirements

• First of all, we will use macos
• brew knowledge
• macOS Terminal iterm
• text editor for code: sublime text

Step 01: configure RVM

• open a terminal and check rvm -v
• compare version with the latest version
• If you need to update, follow these steps
• If you need to install, follow these steps

Step 02: configure RUBY

• open a terminal and check ruby -v
• compare version with the latest version
  • run these commands
  • rvm install RUBY_VERSION
  • rvm use RUBY_VERSION
  • rvm --default use RUBY_VERSION
  • note: RUBY_VERSION=x.x.x

Step 03: configure RAILS

• check rails version
• run these commands gem install rails -v x.x.x (note: RAILS_VERSION=x.x.x)

Step 03: install RAILS

• run these commands rails new ExampleApp (note: RAILS_VERSION=x.x.x)
• You can see all of the command line options that the Rails application generator accepts by running rails new --help.

Step 04: Hello World

• run these commands
• `cd ExampleApp`
• `./bin/dev`
• open a browser window and navigate to http://localhost:3000

Finally we have installed a new rails project with the latest available versions. I hope it helps you
