Padrino mit MySQL, Rake schlägt fehl

Question

Ich möchte einfach den neuen Rahmen Padrino ausprobieren.Ich habe die angegebenen Schritte befolgt Hier.Ich stecke beim Ausführen der Rake-Aufgaben fest.Als Datenbank habe ich MySQL verwendet.Ich habe das Projekt mit dem Befehl erstellt.
padrino g project sample_blog -t sollte -e haml -c sass -s jquery -d activerecord -a mysql padrino g admin

Ich habe alle Abhängigkeiten in der richtigen Reihenfolge, das habe ich getan Bundle-Installation um es zu gewährleisten.Wenn ich dann die Rake-Aufgabe ausführe, erhalte ich diese Fehlermeldung.

$ padrino rake ar:create --trace
=> Rake wird ausgeführt ar:create --trace ...
