Rails 2.3.2アプリケーションを実行中にrakeでPsych構文エラーが発生する

Question

Rubyバージョン1.9.3p551（RVM上）でRails 2.3.2アプリケーションを開発中です。私はこの古いアプリケーションを実行しようとしているときにrake db：migrateやrake -vなどを実行しているときに「Psych Syntax Error」を受け取っています。エラーが発生しています。私を助けてください。私が得たエラー・ログには、次のとおりです。

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

それはconfig/locales内に位置しているローカライゼーション・ファイルの1に構文エラーのように見えます。トレースは、ファイル名を指定しない - あなたは--traceでタスクを実行してみることができます。また、ファイルのそれぞれを解析しようとすることができます

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 

あなたのレールのルートDIRECTRYにファイルにこれを配置し、それを実行しますかruby locale_linter.rbまたはこれをコピーして通常のirbコンソールに貼り付けます。

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"]

出力は、問題のあるファイルにあなたを指している必要があります
