Strange Error

Rails
1

Hi!

I’m reading the ‘Agile Web D. with Rails’ book and I tried to
write the depot application. But almost at the beginning everything
goes wrong and my application doesn’t work. When I try to open
http://localhost:3000/admin with my Firefox, a blank site comes up. This
is the first mistake. And then the window of my WEBrick shows some
strange error - messages (see below). What’s wrong an what can I do to
fix this problem?

Thanks in advance ALEX

Have you run: “rails depot” followed by “ruby script/generate scaffold
Product Admin” ?

Yes, I have! I’ve done everything like it is described in the book and I
don’t know where the mistake is!?

I found my mistake! IRB was not installed, but now it works without any
problems party!
