The Non API version...

• Set Ruby version

Get this into a git repo

git init && git add -A && git commit -m "Initial"

Setup Rspec

Since I always forget this...

bundle exec rails generate rspec:install
bundle exec rake db:migrate && bundle exec rake db:test:prepare

Looks like rails _4.2.7.1_ doesn't work for Rails 5.2.1.

This workaround might help

# make directory for new rails app
mkdir app
cd app

# specify ruby version 
echo 2.3.5 > .ruby-version

# initialize bundler (creates Gemfile)
bundler init

# specify rails version in Gemfile
gem "rails", "4.2.11"

# create rails app using specified version, and overwrite current Gemfile
bundle exec rails new . --force
