Redmine

I was installing a "agile plugin" on redmine 2.4.2. (agile plugin version is 1.3.11: redmine_agile-1_3_11-light.zip)
But there is one problem.
When I try to execute below command, error was popped up!
<command> sudo bundle exec rake redmine:plugins:migrate RAILS_ENV=production
<error> rake aborted! No such file to load -- agile_rank

Here are all messages about error.
