That's the one, thanks. I was looking for it as part of bundle but you are right, emptying the gemset is what I want to do. > > Below I show a log of `bundle install`, `rvm gemset empty` and `bundle > install` After the empty I had to "gem install bundler" before "bundle install" as it took that out too. Otherwise exactly as you show. Many thanks Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
