I am trying to learn rails from "Agile Web Development with Rails, 3rd
Edition" and am having troubles.  I get an error when I try to run this
command on pg 68:

ruby script/generate scaffold product \ title:string description:text
image_url:string

after the “exists test/unit/” result in the dommand window, it says
“wrong number of arguments (1 for 2)”

It means that I cannot progress past page 68. What am I doing wrong?
