Rails应用程序不会部署到heroku

Question

I am trying to push my app to heroku but i keep getting errors. I see that heroku doesnt support sqlite3 and I removed it from the gem file, then bundled. My database.yml file is using postgresql. Maybe something else is trying to use sqlite? How do I fix this issue? Below is the log from heroku after the following command.

$git push heroku master

Answer 1

I have answered this question before in a similar post . Doing a simple search would have gotten you the answer instead of asking right away. Anyways heres the solution.

Just do this in your Gemfile

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

and shift your sqlite3 gem to

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

run bundle install --without production and you should be good to go. Remember to push your new code to git before trying to push to Heroku.
