MySQLproblem - RAILS_ENV=production bundle exec rake db:migrate

Ich bin nur die Installation des redmine zu meinem server durch ausführliches Handbuch. Alles gut gegangen, aber einer der letzten Schritt fehl, mit einigen bug-und ich habe keine Ahnung wie es zu lösen ist.

Befehl ist

RAILS_ENV=production bundle exec rake db:migrate

Ausgabe-Fehler
