ruby & rvm - how to install a “p” version of ruby

Question

How can I use rvm to install a specific version of Ruby, eg 1.9.3p327 instead of the current 1.9.3p194 that I have.

All the references and document are about the major version, eg rvm install 1.9.3 but don't mention the 'p' minor version numbers.

I tried

$ rvm install 1.9.3p327
Unknown ruby interpreter version: '1.9.3p327'.
Could not detect ruby version/name for installation, please be more specific.
$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux]
$ rvm install '1.9.3p327'
Unknown ruby interpreter version: '1.9.3p327'.
Could not detect ruby version/name for installation, please be more specific.

Answer 1

Turned out to be a dash ! $ rvm install 1.9.3-p327

Answer 2

rvm install 1.9.3p327 should work without single quotes.

EDIT: The following option is now deprecated.

Alternatly, to install a patch specific level you could use the -l option. For example

rvm install 1.9.3 -l 327
