Which version to download?

If you don’t know what version to install and you’re getting started with Ruby, we recommend that you use the Ruby+Devkit 2.7.X (x64) installer. It provides the biggest number of compatible gems and installs the MSYS2 Devkit alongside Ruby, so gems with C-extensions can be compiled immediately. The 32 bit (x86) version is recommended only if custom 32 bit native DLLs or COM objects have to be used.

How to update?

Ruby can be updated to the latest patch version (e.g. from 2.6.1 to 2.6.4) by running the new installer version. Installed gems are not overwritten and will work with the new version without re-installation. It’s sufficient to use the RubyInstaller without Devkit for these update installations. The Devkit can be updated separately using the ridk install command.

If the new Ruby version is from a different stable branch, then please use a new target directory for installation. That is to say, a previous RubyInstaller-2.6.x installation should not be updated by installing RubyInstaller-2.7.x into the same directory. This is because gems with C extensions are not compatible between ruby-2.6 and 2.7. Find out more in the FAQ.

RubyInstaller-head

RubyInstaller-head is a daily-updated version of the Ruby development branch. It can be used for continuous integration tests (CI) on your gems or applications, so you’re prepared for upcoming changes to the Ruby core. Builds are available on stable download URIs in the github release section. They can be easily integrated into Appveyor.

With Development Kit?

RubyInstaller uses the MSYS2 toolchain as its development kit. It is bundled into the Ruby+Devkit installer version as a selectable component, so that no additional downloads/installs are required. It’s possible to share one Devkit among multiple versions of Ruby.

MSYS2 is required in order to build native C/C++ extensions for Ruby and is necessary for Ruby on Rails. Moreover it allows the download and usage of hundreds of Open Source libraries which Ruby gems often depend on.

The MSYS2 development environment can be activated in a running cmd or powershell console by ridk enable . This adds commands like make , gcc , pacman or sh to the search path. See more in the Wiki.

Speed and Convenience

RubyInstaller is compiled with the latest GCC at the release date. The installed Ruby is a native Windows application but combines this with the rich UNIX toolset of MSYS2 and the large repository of MINGW libraries.

Documentation

The Ruby core- and standard library documentation are included as part of the installation. We also recommend the online documentation, or the HTML version downloadable from ruby-doc.org.

How to install and use Ruby on Windows

Why install Ruby

Ruby is a scripting language, that is, pre-compilation is not required to run programs. In this sense, Ruby is an analogue of PHP, Python, PERL and others.

Ruby is a fairly popular language and many interesting programs are written on it; in scope of InfoSec, the well-known WPScan, WhatWeb, Wayback Machine Downloader and others can be cited as examples.

By installing Ruby on Windows, you can run programs written in this language, as well as learn this programming language and write your own scripts.

By the way, Ruby, like PHP, Python and PERL, can be a web server module, and scripts written in this language can be used as backend of a website or service.

How to install Ruby on Windows

There you will see many installer options that differ not only in versions, but also in the composition of the downloaded files. Executable files are self-contained installers for Windows that include the Ruby language, runtime, important documentation, and more. If you do not know which version to install in order to get started with Ruby, the Ruby+Devkit * (x64) is recommended. It provides the largest number of compatible gem (Ruby packages) and installs MSYS2-Devkit along with Ruby, so gem with C-extensions can be compiled immediately after installation.

Run the downloaded file. In this window we can select the settings:

The installation folder can be left unchanged.

Add Ruby executables to your PATH – means adding a directory with Ruby executables to the system variable. This is recommended to do for in future to avoid specifying the full path to the script interpreter each time the Ruby script is run.

Associate .rb and .rbw files with Ruby installation. Thanks to this, Ruby files can be launched by double-clicking or by typing the name of the script on the command line.

Use UTF-8 as default external encoding.

I selected all three checkmarks and entered C:\Ruby26 as the installation folder:

As you can see on the next page, the Ruby package itself takes up a bit of space, but the MSYS2 development toolkit offered for installation takes up a lot of space. I highly recommend installing MSYS2 because, in addition to the ability to compile packages for Ruby mentioned above, MSYS2 provides a console environment with Linux features (something like Cygwin does, but with additional features).

Leave a checkmark on the last window to configure the MSYS2 developer tools and click Finish.

Further we are offered:

Just press ENTER to complete all three actions:

Everything is completed, to exit, press ENTER:

By the way, if you carefully watched what was happening on the screen, you might notice pacman. There really is a pacman package manager in this console environment. We will return to other functions of MSYS2 a bit later.

How to update Ruby on Windows

To upgrade to the latest patch (that is, the minor version, for example from 2.5.1 to 2.5.4), it is enough to launch a new version of the installer. Installed gem (packages from the Ruby repository) are not overwritten and will work with the new version without reinstalling. To upgrade the installation, just use RubyInstaller without Devkit. You can update Devkit separately by running the following command at the Windows command prompt:

When a new major version is released, it cannot be updated by installing it in the same directory as the previous one. For example, if the previous version of the installation is RubyInstaller-2.5.x, and the new version is RubyInstaller-2.6.x, then you need to install it either in a new directory or delete the old version and install a new one instead, since gem (programs) with C extensions are not compatible between ruby-2.5 and 2.6.

How to install and use gem on Windows

RubyGems is a package manager for Ruby. Using it, you can install various programs and their dependencies, installation can be done both from the source code on the local system, and from remote application sources.

The Ruby installation shown above also installs gem:

What is MSYS2. How to use MSYS2

We have already installed MSYS2 in order to gain access to compilation tools, thanks to which we can install any Ruby package. In fact, MSYS2 is based on Cygwin and contains a large number of Linux utilities.

MSYS2 provides a shell for bash, Autotools, make, gcc, pacman, sh, and many other packages. Of particular note is the pacman package manager.

To activate the MSYS2 working environment, open a command prompt or powershell console and run there:

As a result, many Linux utilities will immediately become available for work, as well as the Pacman package manager, with which you can install new packages or update existing ones. When installing packages, Pacman monitors the dependencies and installs them.

To update all packages:
