Installing Ruby  Go to http   rubyinstaller org downloads   Make sure that you check  Add ruby     to your PATH     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

Another way is to let chocolatey manage your ruby package  and any other package   that way you won t have to put ruby in your path manually    Install chocolatey first by opening your favourite command prompt and executing    powershell -NoProfile -ExecutionPolicy unrestricted -Command  iex   new-object net webclient  DownloadString  https   chocolatey org install ps1      amp  amp  SET PATH  PATH   systemdrive  chocolatey bin   then all you need to do is type  cinst ruby   In your command prompt and the package installs   Using a package manager provides overall more control  I d recommend this for every package that can be installed via chocolatey
