2, download the Devkit file, then unzip the installation, choose the directory you want. (The order of this step is very important, otherwise the 4th step may be wrong)

Gems are often encountered when installing or upgrading under Windows

Please update your PATH to include build tools or download the DevKit from ‘http://rubyinstaller.org/downloads‘ 
and follow the instructions at ‘http://github.com/oneclick/rubyinstaller/wiki/Development-Kit‘


That's because there's no devkit installed.
