I'm getting
! Taps Load Error: cannot load such file -- sqlite3
even though I have 'sqlite3' installed My database.yml is set to use Postgres in all environments
Ruby is 1.9.3p125
Heroku doesn't support sqlite3.
So you need to change your Gemfile to be:
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
end
And run bundle install
again
