ruby​​/railsでrakeを使用してYAMLを解析する際にエラーが発生する

Question

Ruby/Railsの新機能で、フレームワーク内でmysqlデータベースを使用するWebページを設計するプロジェクトに取り組んでいます。私はレールを正しく動作させるために多くの問題を抱えていましたが、1つの問題がレイクにあると確信しています。コマンドを実行すると、約300行戻ってルビインタープリタがクラッシュします。

私の主な関心事は、私は、コマンドに

rake -v 

を実行したときに、私はYAMLの事は大きな問題のほんの小さな部分である

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

を得るということです。レーキがなぜ全く働いていないのか分かりません。

Answer 1

、私はRubyGemsので使うYAMLパーサはサイケであるため、それが起こると思いますが、レールはSyck必要があります。

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