Question

I’ve got a strange error with a rails 3.0.3 application running on ruby 1.9.2, as a matter a fact it doesn’t run yet, beacause I get the following error:

ArgumentError (Syck is not missing constant BadAlias!):


Rendered /usr/local/lib/ruby/gems/1.9.1/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.0ms)
Rendered /usr/local/lib/ruby/gems/1.9.1/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (14.4ms)
Rendered /usr/local/lib/ruby/gems/1.9.1/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (19.4ms)

Is because of the ruby version? Or how can I solve this?

— later edit:
On ruby 1.8.7 EE, I have no such error.

Answer 1

After searching and searching the internet, I started to look at all my YAML in my app, and I validate each file using: http://yaml-online-parser.appspot.com/, and I’ve got errors like:

while parsing a flow node
expected the node content, but found ':'
  in "<unicode string>", line 147, column 13:
        order: [:day, :month, :year]

Therefore everything was because the yaml errors. The problem is with unicode, in seems that its different on ruby 1.9.2 than in 1.8.7.
