Ruby on Rails - “Add 'gem sqlite3'' to your Gemfile”

Question

I\'m a complete n00b on Rails with only beginner knowledge of Ruby. I plan on studying Ruby more before I really learn Rails, but I\'m waayy too curious for my own good.

Answer 1

1. Don't make another database global and then make sqlite3 specific to an environment on your gem file.
2. Use a previous gem.
3. Make sure you run bundle install, then bundle update, and lastly bundle install.

Your Gemfile might include entries like this:

group :development, :production do
  gem 'pg', '0.15.1'
end

group :test do
  gem 'sqlite3', '1.3.6'
end
