redmine 2.3.3,can't install 1.0.6 - Githubissues

i've seen all of https://github.com/backlogs/redmine_backlogs/search?q=release_relationship&ref=cmdform&type=Issues but no one helps

also i've searched at http://forum.redminebacklogs.net/ found some related post and wrote there: http://forum.redminebacklogs.net/Support-for-RM-2-3-3-tp4025965p4026098.html

so problem is: when i try to install it with command: bundle exec rake redmine:backlogs:install i see this:

root@ubuntu:/home/redmine/redmine# bundle exec rake redmine:backlogs:install RAILS_ENV=production
2.3.3.devel. You are running backlogs v1.0.6, latest version is 1.0.6
