Do not use .rvmrc files to specify Ruby version and gemset configuration any longer, it's deprecated and not considered by other Ruby version managers such as rbenv.
If you want to migrate an existing .rvmrc you can use rvm rvmrc to .ruby-version.
Put gemset specification into .ruby-gemset.
Creating the .ruby-version file on your own, just make a file containing e.g.
1.8.7
Attention: Don't clutter other developers rvms with several unecessary ruby patch levels
When you use the rvm command
rvm --ruby-version use 1.8.7
it generates a .ruby-version file containing
ruby-1.8.7-p374
Using such a .ruby-version file demands installing a new ruby version for each patch level.
