Installation error "rake aborted" "argument error"

[alexander-st]

Dear all,

I just tried to install the plugin. I also downloaded the ajax_counters and a_common_libs into a new installation of Redmine 3.0.2-0 from Bitnami.
After copying the folders into the plugin folder I used the command
bundle install --without development test postgresql sqlite

Then I used
ruby bin/rake redmine:plugins RAILS_ENV=production

The error appears:
C:\Bitnami\redmine-3.0.2-0\apps\redmine\htdocs>rake redmine:plugins:migrate RAIL
S_ENV=production bundle exec

rake aborted!

Is it because the plugin does not work with this Redmine version or is there another problem?
