bundle−clean − Cleans up unused gems in your bundler directory
bundle clean [−−dry−run] [−−force]
This command will remove all unused gems in your bundler directory. This is useful when you have made many changes to your gem dependencies.
−−dry−run
Print the changes, but do not clean the unused gems.
−−force
Forces cleaning up unused gems even if Bundler is configured to use globally installed gems. As a consequence, removes all system gems except for the ones in the current application.
