Unable to push Rails Bootstrap project to Heroku

Question

I'm finished up with the railsapps.org tutorial on Rails and Bootstrap. I am not able to deploy it to Heroku though. My code is exactly as the tutorial, and I followed the directions exactly in the "Deploy" chapter, but when I run git push heroku master I get the errors below. Any ideas what is wrong?

Regards, Jeff

Answer 1

This has been a problem for others as well...including myself. I solved it by making sure sqlite3 was only in the development group and pushing to github again to update any changes.

Here are some links where it seems others have commented on this problem:

• An error occurred while installing sqlite3 (1.3.7), and Bundler cannot continue

• Errors of pushing rails app to Heroku error occurred while installing sqlite3, and Bundler cannot continue

Answer 2

Ok, so weird... I ended up destroying the Heroku app and recreating it. That solved the problem it seems.

Answer 3

According to the book, your Gemfile should look like this:

source 'https://rubygems.org'
ruby '2.1.1'
gem 'rails', '4.1.1'
gem 'sass-rails', '~> 4.0.1'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0',          group: :doc
gem 'spring',        group: :development
gem 'activerecord-tableless'
gem 'bootstrap-sass'
gem 'google_drive'
gem 'high_voltage'
gem 'simple_form'
group :development do
  gem 'sqlite3'
  gem 'better_errors'
  gem 'binding_of_caller', :platforms=>[:mri_21]
  gem 'quiet_assets'
  gem 'rails_layout'
end
group :production do
  gem 'pg'
  gem 'thin'
  gem 'rails_12factor'
end

Make sure gem 'sqlite3' is in the development group. SQLite is not supported on Heroku so you don't want Heroku trying to install it.
