Rails 6 (beta 3) is out and many clients are asking to upgrade to the latest version. Remember, Rails 6 is still in it’s beta version. If you start a project, I would recommend to use stable version of rails i.e. Rails 5.2.x.
But If you want to start with Rails 6 then Rails 6 require Ruby version 2.5+.
If you are using RVM check your ruby version is greater than or equals to 2.5.0 then you can install rails 6 by creating a folder (say folder name is clecotech), then go to that folder and create a Gemfile with writing source and gem rails using below command.
$ mkdir clecotech
$ cd clecotech
$ echo "source 'https://rubygems.org'" >> Gemfile
$ echo "gem 'rails', git: 'https://github.com/rails/rails.git'" >> Gemfile
$ bundle install
You will see below lines after running bundle install command:
Fetching gem metadata from https://rubygems.org/.........
Using rake 12.3
After running bundle command run below command to create project files and folders
$ bundle exec rails new . --dev --force
run git init from "."
After creating folders structures and configuration file you just have to start the rails server from the command below:
$ bundle exec rails server -d
=> Booting Puma
=> Rails 6.0.0.alpha application starting in development
=> Run `rails server --help` for more startup options
Your rails 6 project is started and running.
