Usage: rvm gemset [action] rvm --force gemset [action] Actions: copy, create, delete, dir, empty, export, gemdir, globalcache, import, install, list, list_all, name, pristine, rename, unpack, update, use Description: Commands for working with and manipulating gemsets within RVM. Any command is run in context of current ruby/gemset; call 'rvm current' to find out which is currently used. Note that 'system' supports only exporting/importing gems. Rejection: If you do not want to use gemsets and want to ignore them you can use command line flag `--ignore-gemsets`: rvm use 1.9.3@my_project --ignore-gemsets it will ignore @my_project and @global - only default gemset will be set. It can be persisted with: echo "export rvm_ignore_gemsets_flag=1" >> ~/.rvmrc
