Bundler Error - Cannot Find rake-13.0.1 even though it is installed
Changed the dockerfile from FROM ruby:2.6 to FROM ruby:2.6.0. Using ruby:2.6 appears to be pulling 2.6.5. I deleted the gemfile.lock and and a bundle install to reset the gemfile.lock. Currently it is showing one version of bundler 1.17.2 and everything is working normally again. For anyone else that sees this I believe their is issues with bundler 2 and rubygems.
