title: ruby command is not recognized on Windows (The system cannot find the path specified)
body: <p>After a fresh install of ruby for Windows 64x, I was able to install gems with no problem, but the &quot;ruby&quot; command itself is not recognized, which I need to setup ruby devs and install jekyll.</p>
  <p>EDIT:</p>
  <p>In case someone else is in my situation, the thing that finally worked for me was to uninstall ruby and make a clean installation with the 2.2.6 version of the installer (<a href="https://rubyinstaller.org/downloads/" rel="nofollow noreferrer">https://rubyinstaller.org/downloads/</a>). Then I was able to install Sass, Ruby devKit and Jekyll. The executable of Ruby 2.4.3 just won't work.</p>
