Problem with Ruby 1.9.3 RC1 and YAML files

ruby-talk
1

I am trying to get ruby 1.9.3 rc1 to work and it fails because of my
yaml files:

psych.rb:154:in `parse': (/test/system.yml): couldn't parse YAML at line
0 column 0 (Psych::SyntaxError)

If I do this however:

  YAML::ENGINE.yamler = 'syck'

And then load the same yaml file, everything works.

Now the problem is ...

I do not know why psych hates my yaml files and I do not know
whether it is easy to fix. But my yaml files are critical,
and I would rather simply want to use syck and not bother about
psych.

Is that possible or am I stuck now?

Ideally, what I would love to tell ruby would be to permanently
use sykc as the YAML Engine to use and completely ignore psych
everywhere. But I do not want to do this:

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

In all my .rb files that need to use yaml ...

HELP!

Does your yaml files contains tabs or UTF BOM identifications?

Please include a sample of your YAML files so we can do testing.

Psych is the default YAML parser of 1.9.3, issues with it should be
addressed (if valid)

Either you stick to 1.9.2 and Syck or help us solve any possible issue
with YAML files.

It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.

See line 10, 11 and 14. Is this the way it must be?
