I’m new to Rails and Ruby, and am also using cmd instead of Unix or Emacs. The only problem I had after installing was that the directory C:\Ruby192\bin wasn’t automatically added to the path variable. To add it to the path, run this command in cmd:
path=percent signPATHpercent sign;C:\Ruby192\bin
So far, very happy with this book and look forward to learning more.
Edit: Not sure how to add a percent sign, since the escape characters I know aren’t working.
