Error when starting WEBBrick

Hi… I installed Ruby On Rails on ubuntu and when I try to start the server I get the following:

felipe@balthazar:~/teste$ ruby script/server
=> Booting WEBrick…
/usr/local/lib/ruby/1.8/yaml.rb:133:in load': syntax error on line 31, col -1: ’ (ArgumentError)
from /usr/local/lib/ruby/1.8/yaml.rb:133:in `load’

    from ./script/../config/../vendor/rails/railties/lib/commands/server.rb:30
    from script/server:3:in `require'
    from script/server:3

This error occurs also when I try to create a scaffold.

line 133 of yaml.rb goes like this:

132: def YAML.load( io )
133: yp = parser.load( io )
134: end

I have no ideia of what is going on here, does anyone there has?
I am trying to run a single application since sunday but I had no success of making Rails work on linux. On the other hand, I had no problems in making it work on Windows XP (althought I still didn’t get how to set a Rails application up on Apache2). I would like very much to be able to work on linux, but all these things are driving me to just give up :(.

Thanks for your attention,

Felipe

Hi!

I’m a newbie to this, just installed it; but have u set up your database correct in your teste/config/database.yml?
