I have started getting this error when pushing my Ruby on Rails app to Bluemix. My app doesn't actually need a database, but I have the following in database.yml:
default: &default
adapter: sqlite3
pool: 5
timeout: 5000
development:
<<: *default
database: db/development.sqlite3
test:
<<: *default
database: db/test.sqlite3
production:
<<: *default
database: db/production.sqlite3
And in my Gemfile:
gem 'sqlite3' # Use sqlite3 as the database for Active Record
group :production do
gem 'rails_serve_static_assets'
end
These are the errors I get:
Could not detect rake tasks
ensure you can run `$ bundle exec rake -P` against your app with no environment variables present
and using the production group of your Gemfile.

###### WARNING:
You have not declared a Ruby version in your Gemfile.
To set your Ruby version add this line to your Gemfile:
ruby '2.2.3'
Looks like RAILS_ENV variable is not set. I have not used Bluemix so not sure how to export variables there. If you don't need database, you don't have to include activerecord. see following thread for more details on how to remove activerecord.
