RoR Michael Hartl Tutorial (3rd) - An error occurred while installing sqlite3, and Bundler cannot continue

Question

Others have asked a similar questions before but none have been using the cloud9 IDE. I have tried solutions to other questions, but still can't get it to work.

I am doing the Michael Hartl Ruby on Rails Tutorial (3rd) and using the cloud9 IDE (as I run Windows OS).

When I try to push my master branch from Bitbucket to Heroku.

$ git push heroku master

I get the error:

An error occurred while installing sqlite3 (1.3.11), and Bundler cannot continue.

I appreciate that Heroku does not support sqlite. But I have followed the tutorial very closely. And I can't see where I have gone wrong.

Here is the full code:

Any help would be much appreciated, thanks.

Answer 1

Heroku works only with PostgreSQL. You can continue to use sqlite3 locally, but you need to switch to pg on Heroku.

group :development, :test do
    gem 'sqlite3'
    end
group :production do
  gem 'pg'
end

Then delete

`Gemfile.lock`

Then run

bundle install --without production

Do not forget to commit both Gemfile and Gemfile.lock to the local master before pushing to Heroku.

Answer 2

did you update your Gemfile.lock before pushing? if not to update it run bundle update . good luck mate!

Answer 3

Reading the same book! I experienced the same issue. I fixed it by making sure the gems outside the groups in the Gemfile file did not include sqlite3 (above of development and production), sqlite 3 should only be placed once and under the development group. If you tried to deploy you app to heroku it can cause issues. To fix it, make sure sqlite is only listed like:

group :development, :test do

 .
 .
gem 'sqlite3'
 .
 .

end

and then proceed delete the Gemfile.lock (since a mistake was made, sqlite3 will be listed as a dependency in the Gemfile.lock and it will need to be re-created was deleted by doing a bundle install), next do a bundle install:

bundle install --without production

(--without production is placed so we don't install locally gems that we wont need) Finish by adding, committing and pushing your changes and then deploying it to heroku. You shouldn't have any issues now.
