heroku push error: “Could not detect rake tasks”

Question

I\'m trying to deploy a basic app and it\'s not working. Using

git push heroku master 

I got this error message:

remote:          


        

Answer 1

You may also want to add PG Gem file in production in your gem file

GemFile

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

group :development do
 gem 'sqlite3'
end

OR:

# Use sqlite3 as the database for Active Record
gem 'sqlite3', group: [:development, :test]

gem 'rails_12factor', group: :production
gem 'pg', group: :production

Once you added that there save and run the following:

Terminal

gem install bundler
bundle install
git add .
git commit -m "Some comment here..."
git push heroku master
