Does anyone meet this problem before? Thanks!

Thanks for your reply. Any idea what could be the reason?

Well, what’s on those lines in the routes file that it’s complaining
about? Is there something inappropriate going on with a Hash?

I don’t think there is anything to do with Hash in those code…

it looks (as a guess) that the call to move, instead of tumbling
through to method_missing and created a named_route is calling a
method defined by rake. Does changing the name of the route make any
difference?

Thanks for all the replies. It turns out there is something wrong with
the line 58 in routes.rb. So i commented this line, and it works:-)

Thank you all.
