Hi,

New to RoR and have been assigned a pretty hefty task. I have to alter  
some source code for a company, the only problem is when I import the  
project (using Netbeans) and use terminal to start the server (same  
error for mongrel and Webrick) I get this error explosion:

Anyone know why I’m getting this error ? I can’t really seem to find  
specific reasons after searching for quite some time.

p.s.

hopefully this is the right forum, if not I’d appreciate being pointed  
in the right direction 🙂

Seriously? It mean exactly what it says: the app requires the ‘prawn’  
gem.

Open a terminal window and type gem list --local

If prawn’s not in that list, install it. ( sudo gem install prawn )
