Note: This article is about upgrading RVM to its latest Gem version. Slightly more useful is to upgrade to its newest version directly from Git. For more about upgrading to the latest Git version, see Upgrading to RVM Head.
Since RVM is still in its early stages (current version as of this writing is 0.1.40), it’s still undergoing changes regularly. To keep up to date, it’s recommended that you upgrade your RVM version regularly.
Upgrading RVM is not quite as easy as upgrading any other gem. This is because there’s a second RVM environment installed into your home directory that must be upgraded. But it’s usually just one extra step.
