How do I force Bundler to reinstall all of the gems in my gemfile? Or, how do I force Bundler to uninstall all of the gems it installed so I can then reinstall them myself?

I saw rails bundle clean, but this question explains how to remove gems that bundle installed but are no longer in the gemfile.

And How to reinstall a gem using bundler explains how to reinstall a single gem. I would like to reinstall all of my gems at once.

Another way to deal with gem problems can be to sudo gem clean instead of reinstalling everything
