NAME

       ruby-build - utility to compile and install Rubies

SYNOPSIS

       ruby-build [OPTIONS...] DEFINITION PREFIX

       ruby-build --definitions

       ruby-build --version

       ruby-build [-h|--help]

       rbenv install [OPTIONS...] [DEFINITION]

       rbenv install [-l|--list]

       rbenv uninstall [-f|--force] 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.

       -f, --force
           When using rbenv-install, force installation of Ruby versions that are already
           installed. When using rbenv-uninstall, uninstall without prompting for confirmation or
           displaying an error message for Rubies that are not currently installed.

       -k, --keep
           Don’t delete source code after installation.

       -p, --patch
           Apply a patch from standard input to the Ruby, JRuby or Rubinius source code before
           executing the ./configure step.

       -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 2.0.0 (MRI, patch level 0) to ~/rubies/mri-2.0.0:

           ruby-build 2.0.0-p0 ~/rubies/mri-2.0.0

       Install Ruby Enterprise Edition 1.8.7 (patch level 2011.03) for rbenv(1):

           rbenv install ree-1.8.7-2011.03

       Install local app-specific Ruby version:

           rbenv install

       Install Ruby from a custom definition into ~/your-ruby:

           rbenv install /path/to/your/own/ruby/definition ~/your-ruby

       Install Ruby 2.0.0-p0, applying the patch in /path/to/some.patch:

           rbenv install --patch 2.0.0-p0 < /path/to/some.patch

ENVIRONMENT

       CC
           Sets the path to the C compiler.

       CONFIGURE_OPTS
           Options that are passed to ./configure when building a Ruby.

       MAKE
           Sets the command used for make.

       MAKE_OPTS
           Options that are passed to make when building a Ruby.

       MAKEOPTS
           Used instead of MAKE_OPTS when MAKE_OPTS is not defined.

       RUBY_BUILD_BUILD_PATH
           Sets the location in which sources are downloaded and built.

       RUBY_BUILD_CACHE_PATH
           Sets the location where downloaded package files are cached.

       RUBY_BUILD_DEFINITIONS
           Adds a colon-separated list of directories to the build definition path.

       RUBY_BUILD_MIRROR_URL
           Sets the root URL of the mirror from which package files are downloaded.

       RUBY_BUILD_ROOT
           If set, overrides the default location from where build definitions in
           share/ruby-build/ are looked up.

       RUBY_BUILD_SKIP_MIRROR
           If set, forces ruby-build to download packages from their original source URLs instead
           of using a mirror.

       RUBY_CFLAGS
           Options that are added to the default CFLAGS when building a Ruby.

       RUBY_CONFIGURE_OPTS
           Options that are passed to ./configure when building a Ruby. In contrast to
           CONFIGURE_OPTS, these are only passed to Ruby and not to any dependent packages (such
           as libyaml).

       RUBY_MAKE_OPTS
           Options that are passed to make when building a Ruby. In contrast to MAKE_OPTS, these
           are only passed to Ruby and not to any dependent packages (such as libyaml).

       TMPDIR
           Sets the location where ruby-build stores temporary files.
