Error in creating generator for 'carrierwave_backgrounder:install'

Question

I am creating a generator for the 'carrierwave_backgrounder:install' to process my image in S3. However, I am stuck in a problem

1. When I just use gem 'carrierwave_backgrounder', I am getting the error

   Could not find generator 'carrierwave_backgrounder:install'. Maybe you meant 'rspec:install', 'exception_notification:install' or 'active_record:model

2. When I use gem 'carrierwave_backgrounder', git: 'https://github.com/lardawge/carrierwave_backgrounder' as per the suggestions given everwhere and run bundle install or bundle update, I am getting the error

   Bundler could not find compatible versions for gem "mime-types": In snapshot (Gemfile.lock): mime-types (= 3.3)
In Gemfile: carrierwave-base64 (= 2.6.1) was resolved to 2.6.1, which depends on mime-types (~> 3.0) carrierwave_backgrounder was resolved to 0.4.2, which depends on mime-types (~> 2.99)

and my bundle-update is also not able to resolve the error. How do I resolve this?

Answer 1

Change the line 'carrierwave_backgrounder',git:'https://github.com/lardawge/carrierwave_backgrounder' to gem 'carrierwave_backgrounder', github: 'lardawge/carrierwave_backgrounder', ref: 'bff7bc3954b9184157812f948b9a6a4f64ff36d3' solves the problem.
