This project provides an Installer for Ruby-2.4 and newer on Windows based on the MSYS2 toolchain. It is the successor to the MSYS1 based RubyInstaller which was used for Ruby-2.3 and older. It is licensed under the 3-clause Modified BSD License.
In contrast to the old RubyInstaller it does not provide its own DevKit, but makes use of the rich set of MINGW libraries from the MSYS2 project. It therefore integrates well into MSYS2 after installation on the target system to provide a build-and-runtime environment for installation of gems with C-extensions. This and more changes are documented in the CHANGELOG.
Using the Installer on a target system
- Download and install the latest RubyInstaller2: https://github.com/larskanis/rubyinstaller2/releases
The non-Devkit installer file is enough to use pure Ruby gems or fat binary gems for x64-mingw32 or x86-mingw32. In order to install C based source gems, it's recommended to use the Devkit installer version. It installs a MSYS2/MINGW build environment into the ruby directory that ships common build tools and libraries.
Some gems require additional packages, which can be installed per
pacman. See below.
Its also possible to install MSYS2 manually from https://msys2.github.io/ and run
ridk install afterwards to add non default, but required development tools.
For unattended install of Ruby and MSYS2 see the FAQ chocolatey install.
ridk is a cmd/powershell script which can be used to install MSYS2 components, to issue MSYS commands like
pacman or to set environment variables for using MSYS2 development tools from the running shell.
ridk help for further options:
Usage: C:/Ruby24-x64/bin/ridk.cmd [option] Option: install Install MSYS2 and MINGW dev tools exec <command> Execute a command within MSYS2 context enable Set environment variables for MSYS2 disable Unset environment variables for MSYS2 version Print RubyInstaller and MSYS2 versions use Switch to a different ruby version help | --help | -? | /? Display this help and exit
ridk enable can be used to enable MSYS2 development tools on the running console.
make etc. available on the command line.
See the Wiki for further instructions to the
Install gems with C-extensions and additional library dependencies
The base MSYS2 setup includes compilers and other build tools, but doesn't include libraries or DLLs that some gems require as their dependencies.
Fortunately many of the required libraries are available through the MSYS2 repositories.
They can be installed per
ridk exec pacman -S mingw-w64-x86_64-libraryname similar to
apt-get on Linux.
Exchange the prefix
mingw-w64-i686 for the 32-bit RubyInstaller.
For instance these popular gems can be installed like so from the source gem:
- To install
sh ridk exec pacman -S mingw-w64-x86_64-sqlite3 gem install sqlite3 --platform ruby
- To install
sh ridk exec pacman -S mingw-w64-x86_64-libxslt gem install nokogiri --platform ruby -- --use-system-libraries
Building the Installer
This repository provides the packaging tasks to build RubyInstaller setup executables and 7zip files. It doesn't compile any sources, but makes use of the MSYS2-MINGW repository and the RubyInstaller2 pacman repository to download binaries and dependent libraries.
Automatic build on Github Actions
The installer is regularly built on Github Actions for each push to the github repository. The runner also executes the installer and runs all RubyInstaller tests and ruby-spec on it, so that we are notified about breaking changes. In addition to this, a daily build of the latest ruby development snapshot is compiled and packaged as RubyInstaller files. It can be downloaded from github releases. Check the wiki on how to use ruby-head versions for your CI builds.
Build RubyInstaller2 on your own machine:
- Make sure you have a working RubyInstaller-2.4+ and Git installation
- Ensure you have MSYS2 installed either by a RubyInstaller-Devkit version or per
ridk installwith default options
- Install the latest Inno-Setup (unicode) from http://www.jrsoftware.org/isdl.php
- Run cmd.exe and add iscc.exe to PATH:
sh set PATH=%PATH%;"c:\Program Files (x86)\Inno Setup 6"
- Clone RubyInstaller2 and install dependencies:
sh git clone https://github.com/larskanis/rubyinstaller2 cd rubyinstaller2 bundle install rake -T
- The last command lists all available RubyInstaller build targets.
The build targets consists of the following parts:
rake ri:ruby-3.0.5-x86-msvcrt:archive-7z ^ ^ ^ ^ ^- "archive-7z" => 7z archive of the rubyinstaller files | | | | "installer-inno" => executable installer file | | | '------- "msvcrt" => older type of C standard library | | | "ucrt" => new type of C standard library | | '------- "x86" => 32 bit ruby and MSYS2 version | | "x64" => 64 bit version | '------ "x.x.x" => ruby version to build | "head" => latest development snapshot of ruby '------ "ri" => RubyInstaller without Devkit "ri-msys" => RubyInstaller with MSYS2 based Devkit
- Copy and paste the interesting one on the command line.
- If everything works well, you will find the final setup and archive files like so:
- It's best to avoid installation into a PATH containing spaces. Some gems won't install.
