環境 Rails 3.2.14 Ruby 1.9.3p448 Ubuntu 12.04 バンドラー バージョン 1.3.5
ruby 1.9.3 が YAML をロードする方法に問題があります。databse.yml ファイルのコードを削除すると、rails console、server、generate などのコマンドが失敗します。これらのデフォルトを削除すると、すべて正常に動作します。
psych パーサーと syck パーサーを試しました。syck パーサーではエラー トレースだけが異なりますが、問題は解決しません。
以下はほんの一例です。実際の構成は異なります。database.yml が次のような場合にエラーが発生します。
default: &default
host: localhost
...
development:
<< *default
pool: 5
...
database.yml ファイルが次のような場合、まったく問題なく動作します。
development:
host: localhost
pool: 5
以下はエラートレースです。
