NAME
ruby-build - compile and install Rubies SYNOPSIS
ruby-build [-v|--verbose] [-k|--keep] definition prefix ruby-build --definitions ruby-build --version ruby-build [-h|--help] rbenv install [-k|--keep] definition DESCRIPTION
ruby-build provides a simple way to compile and install different versions of Ruby on UNIX-like systems. ruby-build downloads, builds and installs the Ruby version specified in a definition into a prefix directory. Definitions can be chosen from the list of installed definitions or by specifying a file path for a definition. rbenv(1) users can also use the provided rbenv install command, which installs Rubies into the rbenv directory. OPTIONS
--definitions List available definitions. -k, --keep Don't delete source code after installation. -v, --verbose Display compiler messages on standard output. --version Show ruby-build version and exit. -h, --help Show usage information and exit. EXAMPLES
Install Ruby 1.9.3 (MRI, patch level 0) to ~/rubies/mri-1.9.3 $ ruby-build 1.9.3-p0 ~/rubies/mri-1.9.3 Install Ruby Enterprise Edition 1.8.7 (patch level 2011.03) for rbenv(1): $ rbenv install ree-1.8.7-2011.03 Install Ruby from a custom definition into ~/your-ruby: $ rbenv install /path/to/your/own/ruby/definition ~/your-ruby ENVIRONMENT
CC Sets the path to the C compiler. CONFIGURE_OPTS Options that are passed to configure when building a Ruby. MAKE_OPTS Options that are passed to make when building a Ruby. MAKEOPTS Used instead of MAKE_OPTS when MAKE_OPTS is not defined. TMPDIR Sets the location where ruby-build stores temporary files. RUBY_BUILD_BUILD_PATH Sets the location in which sources are downloaded and built. AUTHORS
