Which version to download?
How to Install Ruby on Mac OS X with RVM. This article explains why you should avoid using the version of Ruby bundled with Mac OS X and should instead install your own version of Ruby with RVM, the Ruby Version Manager. Hands Off the System Ruby. Apple bundles the Ruby programming language with OS X. However, the main caveat for using the. Install a new Ruby with rbenv on Mac OS (and make yourself a superhero) If you're doing stuff with Ruby on a Mac, e.g. Installling Jekyll or something, by default you'll end up having to use the sudo command to do stuff, since the permission to modify the default config is not available to your user account. Mac has basically Ruby. So, you can install Rails directly, but to support various versions of Ruby, we’ll install rbenv that is ruby version manager. Execute the command below to install rbenv.
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.
