ruby is not recognized....
as an internal or external command, operable program or batch file.
I keep getting the about error message when trying run the first few ruby commands in the book, hello.rb and numbers.rb. The frustrating part is that I was able to get hello.rb to work at first but not now. Rails is running. One suggestion I has was that my system doesn't know where to look for ruby. I tried that correction but it still isn't working.
