I’m newbie and installed Rails last week. When I did rails -v in cmd prompt, I got this:
ruby 2.0.0p0 (2013-02-24) [i386-mingw32]
‘rails’ is not recognized as an internal or external command,
operable program or batch file.
I want to upgrade or install Rails 4. Does this mean I don’t have Rails installed? I used RailInstaller 3.0 last week to install Ruby on Rails.
