Detected sqlite3 gem which is not supported on Heroku

Question

I\'m trying to push my rails app to Heroku, and I keep getting the following error:

       An error occurred while installing sqlite3 (1.3.8), and Bundler ca         


        

Answer 1

Try using this for production

group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor'
end

Additional information can be found here: https://devcenter.heroku.com/articles/sqlite3

Answer 2

I have modified the gem file to use sqlite only on development, and test.

But, my mistake was: I have forgotten to commit the changes on git.

Answer 3

You have a typo:

group :development, :test do # <<<< :development, not devlopment
  gem 'sqlite3'
end

As heroku ignores development specific gems, when running the bundle it includes sqlite3 gem.

Answer 4

Try this

heroku rake db:reset
heroku rake db:migrate
