IRB error message (dyld: NSLinkModule() error)

Hi folks, I'm new to Rails. I picked up Simply Rails 2 by Patrick Lenz a few weeks ago and I finally sat down to get stuck into it. I have Rails installed on my iMac (OS X Leopard) and I can load up the Rails Welcome screen at localhost:3000 without any issues.

My problem is with running IRB within Terminal.

If I try to run:

1

I receive the error: dyld: NSLinkModule() error dyld: Symbol not found: _rl_filename_completion_function   Referenced from: /usr/local/lib/ruby/site_ruby/1.8/i686-darwin9.5.0/readline.bundle   Expected in: flat namespace

Trace/BPT trap

I have no idea why this is appearing or how to fix it.

My setup is: Ruby version 1.8.6 (i686-darwin9.5.0) RubyGems version 1.3.0 Rails version 2.1.2 Active Record version 2.1.2 Action Pack version 2.1.2 Active Resource version 2.1.2 Action Mailer version 2.1.2 Active Support version 2.1.2 Application root /Users/cormacmoylan/shovell Environment development Database adapter sqlite3 Database schema version 0

Thanks for any assistance in the matter. C.

hi Excellent book by the way Also highly reccomend railscasts.com

Yeah, the book seems solid enough. Thanks for pointing out trailscast.com too. Looks v.handy.

Now Are you running from your site dir ./script/console ?

You are passing nothing meanningful to the console

Yes. 1 is a number but it has to follow some method like 1.class

Which will return >> fixnum

I am running the irb> 1 command from a directory called shovell.
