ruby -v
I recommend using Chocolatey to manage your ruby installation.
It's a unix style package manager for windows.
It's quite easy to install, you can find instructions on their website.
In cmd.exe (run as administrator):
@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin
Then you can install ruby:
choco install ruby
And upgrade it later:
choco upgrade ruby
Either You can go with new Installer or use "gem"(ruby package manager) to update.
The easiest way for you might be to use RubyInstaller, which its version 2.0.0-p0 is now available for download as installers. Follow the link http://rubyinstaller.org/ for more information.
