Rails: unable to deploy to Heroku - ruby-on-rails

Question

UPDATE: Even though I'm completely removing sqlite3gem from my Gemfile and Gemfile.lock, it is still being installed on heroku.
I'm trying to deploy my Rails app to Heroku, and even tho I followed the instructions, I get the infamous sqlite3 error:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

The problem is that I have exactly the same Gemfile and Gemfile.lock that I had with a similar project, and this was successfully deployed to Heroku.
Here's my Gemfile:
source 'https://rubygems.org'

And my Gemfile.lock, which indeed contains the sqlite3 gem:

Answer 1

sqlite 3 gem cannot be installed in heroku. It is a sample database which comes default with Rails. In case of production, you will have to use some advanced database. Please check this link for more info https://devcenter.heroku.com/articles/sqlite3

Answer 2

Unfortunately I was trying to push to heroku without having committed my changes. Thanks everybody for the help!

Answer 3

Heroku provides Postgresql databases as services for your apps. Read here, why it is not a good idea to use sqlite3 in production mode.
So you need to change your Gemfile to something like this:
group :production do
# postgresql
gem 'pg'
# enabling features such as static asset serving and logging on Heroku
gem 'rails_12factor'
end
group :development, :test do
# SQLite3 Database
gem 'sqlite3'
...
end
