We have several tools on each major platform to install Ruby: On Linux/UNIX, you can use the package management system of your distribution or third-party tools (rbenv and RVM). On macOS machines, you can use third-party tools (rbenv and RVM). On Windows machines, you can use RubyInstaller. See the Installation page for details on using package management systems or third-party tools. Of course, you can also install Ruby from source on all major platforms. Compiling Ruby — Source Code. Installing from the source code is a great solution for when you are comfortable enough with your platform and perhaps need specific settings for your environment. It’s also a good solution in the event that there are no other premade packages for your platform. See the Installation page for details on building Ruby from source. If you have an issue compiling Ruby, consider using one of the third party tools mentioned above. They may help you.

Ruby versioning with (RVM) If you are not very experienced with Ruby Version Manager (RVM) and are into exploring different rails applications, cloning people’s github repositories and reading through their code, you might have encountered situations where your Ruby or Rails versions clash. For example, what happens when one project requires a lower version of Ruby than the ruby version installed on your computer? Do you downgrade the Ruby version installed? Maybe. But what if you install another ruby project, that requires a newer version? You may get caught up in the loop of constantly upgrading and downgrading. RVM is the answer in such situations. RVM is a command-line tool which allows you to easily install, manage, and work with multiple Ruby environments. It helps you maintain different versions of Ruby and all your other gemsets separate from the system defaults and other version defaults. A gem is simply how libraries are called in Ruby and a gemset is a compartmentalized independent Ruby setup containing its own gems. RVM usage. Let’s stop talking about it and get to it already, but first, check your version of Ruby by running: To install another Ruby version, let’s follow these steps. Step 1. Install rvm. I’ll refer you to the RVM installation instructions at this point to get the proper instructions for your OS. The steps after this assume that RVM is installed. Step 2. Install another Ruby version using RVM by running: Where 2.4.2 is the version of Ruby you want to install and you can also install as many Ruby versions as you like using the same method. NOTE: While trying to install an older version of Ruby on a macOS high sierra, you may encounter this error. In this case, install openssl. Or run this command if openssl is already installed. Step 3. You can now list the versions of Ruby that are installed by the command below: The output of the above command should look similar to the block below. To use any of the versions, simply type rvm or rvm use and to know which Ruby you are currently using type the command below. You should now see the Ruby version you chose previously. Managing multiple rails versions using RVM. You can then install Ruby on Rails(rails) in the current Ruby version using the command below. So far you are able to have different Ruby versions having one rails version each. But what if you need to have a project using a different version of rails but similar Ruby version? You will need to create a different gemset for each setup. Gemsets. To create new gemsets run the command below: This creates two gemsets with different names rails503 and rails320. To display the gemsets associated with a Ruby version, type the command below. and to use any of the gemsets run, You can now install rails inside this gemset by running the command below. Switching gemsets. In case you want to use a particular gemset associated with the Ruby version that is currently in use, run the command below. To know the name of the gemset you are currently using, simply run the command below. The to list all gemsets for all the Ruby versions installed run, I f you don’t use a gemset at all, you get the gems in the ‘default’ set. If you use a specific gemset (say @rails320), it will inherit gems from that Ruby’s @global. The ‘global’ gemset is to allow you to share gems to all your gemsets. The ‘default’ gemset is used when no specific version is installed. Install Sass. There are a good many applications that will get you up and running with Sass in a few minutes for Mac, Windows, and Linux. You can download most of the applications for free but a few of them are paid apps (and totally worth it) . CodeKit (Paid) Mac Ghostlab (Paid) Mac Windows Hammer (Paid) Mac LiveReload (Paid, Open Source) Mac Windows Prepros (Paid) Mac Windows Linux Scout-App (Free, Open Source) Windows Linux Mac. Command Line. When you install Sass on the command line, you'll be able to run the sass executable to compile .sass and .scss files to .css files. For example: First install Sass using one of the options below, then run sass --version to be sure it installed correctly. If it did, this will include 1.37.5 . You can also run sass --help for more information about the command-line interface. Once it's all set up, go and play . If you're brand new to Sass we've set up some resources to help you learn pretty darn quick. Install Anywhere (Standalone) You can install Sass on Windows, Mac, or Linux by downloading the package for your operating system from GitHub and adding it to your PATH . That’s all—there are no external dependencies and nothing else you need to install. Install Anywhere (npm) If you use Node.js, you can also install Sass using npm by running. However, please note that this will install the pure JavaScript implementation of Sass, which runs somewhat slower than the other options listed here. But it has the same interface, so it’ll be easy to swap in another implementation later if you need a bit more speed! Install on Windows (Chocolatey) If you use the Chocolatey package manager for Windows, you can install Dart Sass by running. Install on Mac OS X or Linux (Homebrew) If you use the Homebrew package manager for Mac OS X or Linux, you can install Dart Sass by running.

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 Github Actions or 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. Read more about RubyInstaller and its alternatives here. 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. Support. Enjoy! Happy Ruby-coding!
