Rails error

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?

is that backslash there in the command you are actually typing ?
