Ruby Version Manager

Ruby Version Manager, often abbreviated as RVM, is a software platform for <a href="/facts/Unix-like/YAKrAxzd">Unix-like</a> operating systems designed to manage multiple installations of <a href="/facts/Ruby_/BeYSaPSR">Ruby</a> on the same device.
The entire Ruby environment including the Ruby interpreter, installed <a href="/facts/RubyGems/GWoWccho">RubyGems</a> (gems), and documentation is partitioned. A developer can then switch between the different versions to work on several projects with different version requirements. In addition to <a href="/facts/Ruby_MRI/rxzL7hAR">MRI</a>, the standard Ruby interpreter, RVM functions as an installer for various other implementations of Ruby. These include <a href="/facts/JRuby/o6baVhhF">JRuby</a>, <a href="/facts/Mruby/tlRnogjY">mruby</a>, <a href="/facts/MacRuby/FQws77kY">MacRuby</a>, <a href="/facts/IronRuby/zfDwlxGn">IronRuby</a>, <a href="/facts/MagLev_(software)/DVPWR8KP">Maglev</a>, <a href="/facts/Rubinius/JHyNjSQg">Rubinius</a>, Ruby Enterprise Edition, Topaz, and GoRuby (an interpreter optimized for <a href="/facts/Code_golf/rEAglhrU">code golf</a>). In addition, RVM supports the installation of patched versions of MRI.
RVM provides features for organization of Ruby gems through "gemsets", collections of gems separated by a namespace and associated Ruby installation. Gemsets can be associated with directories/projects through the use of the RVM-exclusive .rvmrc file. An alternative to using the .rvmrc file (and the general purpose although user-specific .jrubyrc) and its format is use of the .ruby-version and .ruby-gemset files, which are compatible with other ruby version managers, such as RBenv and chruby. Additionally, using .rvmrc requires trusting to prevent execution of unauthorized code, while .ruby-version does not.
