What's Ruby
Ruby is an interpreted object-oriented programming language often
used for web development. It also offers many scripting features
to process plain text and serialized files, or manage system tasks.
It is simple, straightforward, and extensible.
Features of Ruby
- Simple Syntax
- Normal Object-oriented Features (e.g. class, method calls)
- Advanced Object-oriented Features (e.g. mix-in, singleton-method)
- Operator Overloading
- Exception Handling
- Iterators and Closures
- Garbage Collection
- Dynamic Loading of Object Files (on some architectures)
- Highly Portable (works on many Unix-like/POSIX compatible platforms as
well as Windows, macOS, Haiku, etc.) cf.

How to get Ruby
For a complete list of ways to install Ruby, including using third-party tools
like rvm, see:
https://www.ruby-lang.org/en/downloads/
Git
The mirror of the Ruby source tree can be checked out with the following command:
$ git clone https://github.com/ruby/ruby.git
There are some other branches under development. Try the following command
to see the list of branches:
$ git ls-remote https://github.com/ruby/ruby.git
You may also want to use https://git.ruby-lang.org/ruby.git (actual master of Ruby source)
if you are a committer.
Subversion
Stable branches for older Ruby versions can be checked out with the following command:
$ svn co https://svn.ruby-lang.org/repos/ruby/branches/ruby_2_6/ ruby
Try the following command to see the list of branches:
$ svn ls https://svn.ruby-lang.org/repos/ruby/branches/

How to compile and install
-
If you want to use Microsoft Visual C++ to compile Ruby, read
win32/README.win32 instead of this document. -
If
./configuredoes not exist or is older thanconfigure.ac, run
autoconfto (re)generate configure. -
Run
./configure, which will generateconfig.handMakefile.Some C compiler flags may be added by default depending on your
environment. Specifyoptflags=..andwarnflags=..as necessary to
override them. -
Edit
include/ruby/defines.hif you need. Usually this step will not be needed. -
Remove comment mark(
#) before the module names fromext/Setup(or add
module names if not present), if you want to link modules statically.If you don't want to compile non static extension modules (probably on
architectures which do not allow dynamic loading), remove comment mark
from the line "#option nodynamic" inext/Setup.Usually this step will not be needed.
-
Run
make.- On Mac, set RUBY_CODESIGN environment variable with a signing identity.
It uses the identity to signrubybinary. See also codesign(1).
- On Mac, set RUBY_CODESIGN environment variable with a signing identity.
-
Optionally, run '
make check' to check whether the compiled Ruby
interpreter works well. If you see the message "check succeeded", your
Ruby works as it should (hopefully). -
Optionally, run
make update-gemsandmake extract-gems.If you want to install bundled gems, run
make update-gemsand
make extract-gemsbefore runningmake install. -
Run '
make install'.This command will create the following directories and install files into
them.${DESTDIR}${prefix}/bin${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}${DESTDIR}${prefix}/lib${DESTDIR}${prefix}/lib/ruby${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}${DESTDIR}${prefix}/lib/ruby/site_ruby${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}${DESTDIR}${prefix}/lib/ruby/vendor_ruby${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}${DESTDIR}${prefix}/share/man/man1${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system
If Ruby's API version is 'x.y.z', the
${MAJOR}is 'x', the
${MINOR}is 'y', and the${TEENY}is 'z'.NOTE: teeny of the API version may be different from one of Ruby's
program versionYou may have to be a super user to install Ruby.
If you fail to compile Ruby, please send the detailed error report with the
error log and machine/OS type, to help others.
Some extension libraries may not get compiled because of lack of necessary
external libraries and/or headers, then you will need to run 'make distclean-ext'
to remove old configuration after installing them in such case.
