"Rake aborted!" when deploying Treebook to Heroku

The following message is what I got when deploying the treebook application after running

$git push heroku master
Running: rake assets:precompile
       DEPRECATION WARNING: Paths in SQLite3 database URLs of the form `sqlite3:///path` will be treated as absolute in Rails 4.2. Please switch to `sqlite3:dbname`. (called from <top (required)> at /tmp/build_1b216552-cf3a-44eb-85dc-e96afb04dc2a/Rakefile:6)
       rake aborted!
       Gem::LoadError: Specified 'sqlite3' for database adapter, but the gem is not loaded. Add `gem 'sqlite3'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

I've changed the gemfile as instructed to the following:

group :development, :test do
       gem 'sqlite3'

group :production do
    gem 'pg'

I also run the "bundle install" and changed the database.yml file as follow:

  adapter: postgresql
  database: treebook
  pool: 5
  timeout: 5000

However all these do not work, and I get the error message repeatedly. I'll appreciate if anyone can solve this problem. Thanks.

I got the same error. From your notes, it sounds like you might have already tried this, but I followed the instructions here and it worked for me: http://www.jackiejohnston.us/blog/switching-to-postgresql-production-database-for-heroku-deployment/

You also want to setup postgres on your computer (I used brew) and commit the changes in git.
