Psych Syntax Error with rake while running Rails 2.3.2 application

I am working on Rails 2.3.2 application with Ruby version of 1.9.3p551 (on RVM). When I am trying to run this old application, I am getting an 'Psych Syntax Error' that is when I run rake db:migrate or rake -v or any other, I am getting error. Please help me. The error log I got is:

myuser@iam:~/Desktop/practice/Application$ rake -v
rake aborted!
Psych::SyntaxError: (<unknown>): did not find expected node content while parsing a flow node at line 18 column 14

It looks like a syntax error in one of the localization files which are located inside config/locales. The trace does not name the file - you can try running the task with the --trace or you can try parsing each of the files:

require 'yaml'
Dir.glob("config/locales/*.yml").each do |f|
  begin
    YAML.load(File.read(f))
  rescue Psych::SyntaxError => e
    puts "YAML syntax error in: #{f}"
    puts e.message
  end
end

You can either place this in a file in your rails root directry and run it with ruby locale_linter.rb or by copy pasting this into the normal irb console.

The output should point you to the offending file:

Syntax error in: config/locales/en.yml
(<unknown>): did not find expected key while parsing a block mapping at line 23 column 3
=> ["config/locales/en.yml"]
