Installing RubyGems in Windows

Use chocolatey in PowerShell

choco install ruby -y
refreshenv
gem install bundler

Installing Ruby

Go to http://rubyinstaller.org/downloads/

Make sure that you check "Add ruby ... to your PATH". enter image description here

Now you can use "ruby" in your "cmd".

If you installed ruby 1.9.3 I expect that the ruby is downloaded in C:\Ruby193.

Installing Gem

install Development Kit in rubyinstaller. Make new folder such as C:\RubyDevKit and unzip.

Go to the devkit directory and type ruby dk.rb init to generate config.yml.

If you installed devkit for 1.9.3, I expect that the config.yml will be written as C:\Ruby193.

If not, please correct path to your ruby folders.

After reviewing the config.yml, you can finally type ruby dk.rb install.

Now you can use "gem" in your "cmd". It's done!


To setup you Ruby development environment on Windows:

  1. Install Ruby via RubyInstaller: http://rubyinstaller.org/downloads/

  2. Check your ruby version: Start - Run - type in cmd to open a windows console

  3. Type in ruby -v
  4. You will get something like that: ruby 2.0.0p353 (2013-11-22) [i386-mingw32]

For Ruby 2.4 or later, run the extra installation at the end to install the DevelopmentKit. If you forgot to do that, run ridk install in your windows console to install it.

For earlier versions:

  1. Download and install DevelopmentKit from the same download page as Ruby Installer. Choose an ?exe file corresponding to your environment (32 bits or 64 bits and working with your version of Ruby).
  2. Follow the installation instructions for DevelopmentKit described at: https://github.com/oneclick/rubyinstaller/wiki/Development-Kit#installation-instructions. Adapt it for Windows.
  3. After installing DevelopmentKit you can install all needed gems by just running from the command prompt (windows console or terminal): gem install {gem name}. For example, to install rails, just run gem install rails.

Hope this helps.


I recommend you just use rubyinstaller

It is recommended by the official Ruby page - see https://www.ruby-lang.org/en/downloads/

Ways of Installing Ruby

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 OS X machines, you can use third-party tools (rbenv and RVM).
  • On Windows machines, you can use RubyInstaller.
