Steps to install rails 6.0 alpha

rails_6_0_alpha.txt

Pre reqs:

I installed these using homebrew

* nodejs
* yarn

Create an application directory manually

$ mkdir app_name

Cd into the directory and create a Gemfile manuall

$ touch Gemfile

Add the following

---
source 'https://rubygems.org'

gem 'rails', github: 'rails/rails', branch: 'master' # Use rails 6.0.0.alpha, FIXME: to be updated on rails release
---

Run bundler

$ bundle install

Check the rails version is the alpha version

$ rails --version

=> Rails 6.0.0.alpha

Generate the rails internals ('Y' when prompted to overwrite Gemfile)

$ rails new . --dev

Reset the rails pointer from local version back to git repo in Gemfile

From:

---
gem 'rails', path: "/Users/vell/.rvm/gems/ruby-2.5.1/bundler/gems/rails-d1c76dd4b0d3"
---

To:

---
gem 'rails', github: 'rails/rails', branch: 'master'
---

Re-run bundler to set the lockfile

$ bundle install

Run webpacker installer

$ rails webpacker:install

Run the rails server

$ rails s

wow! so much helpful

Thanks for this!
