Im using earnshark_sdk 0.2.0 ruby gem in my app, and now i would like to use the latest version 0.2.1. So i tried doing the following
gem 'earnshark_sdk', '~> 0.2.1'
Answering my own question,
My docker container was not able to detect my gemfile, by defining a default path for the the gemfile in the compose I was able to fix this.
Added a volume mount in docker-compose.yml
volumes: - /e/Workspaces/MyApp/src/Gemfile:/home/app/webapp/Gemfile
