Using rake in ruby/rails and getting an error parsing the YAML

Question

I'm new to Ruby / Rails and an working on a project to design a webpage that uses a mysql database within the framework. I've had a lot of issues getting rails to work properly, but I'm fairly sure one problem is with Rake. When I run the command

    rake db:create:all

it returns around 300 lines, then the ruby interpreter crashes.

My main concern is that when I run the command

    rake -v

I get

    ...
    rake aborted!
    (<unknown>) couldn't parse YAML at line 17 column 14

The YAML thing is just a smaller part of a bigger problem. I'm just not sure why rake isn't working at all.

Edit: Heres the trace.

Answer 1

what about add following snippet code at boot.rb after require 'rubygems', i think it happen because yaml parser that use by rubygems is psych but rails need syck :

require 'yaml'
YAML::ENGINE.yamler = 'syck'
