Is there a way to create the associated .ruby-version and .ruby-gemset files when creating a new gemset?
With older versions of rvm, one could do rvm --create --rvmrc 1.8.7@project, but that creates .rvmrc files.
I thought I read somewhere we could use the --ruby-version command line switch, but I have been unsuccessful in doing so.

I recently had the same problem. rvm --help led me to:
rvm --create --ruby-version ruby-1.9.3@my-gemset
It created both .ruby-gemset and .ruby-version.
回答2:
According to the official RVM docs you can use this:
echo 1.9.3 > .ruby-version
Or you can use this:
rvm --ruby-version use 1.9.3@my_app
The second form will create both .ruby-version and .ruby-gemset.

Suppose I am creating gemset for my rails app whose name is tptapp then we can do it in following way.
rvm use 2.2.2@tptapp --create
here tptapp is name of gemset, 2.2.2 is Ruby version.

All of the above examples require you to type in your ruby version and gemset name .. which is close to the same keystrokes required to vi .ruby-gemset and vi .ruby-version. Assuming you are in a directory where you've already chosen your ruby version and you are pointing at the desired gemset.. this does the trick.
bash# rvm --ruby-version use $(rvm-prompt)
