Redmine

Добрый день! скажите пожалуйста как установить плагин kpi в redmine 4.0.4-1?
делаю по инструкции http://rmplus.pro/ru/redmine/plugins/kpi/manual во время установки bundle install выходить ошибка
_Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application
for all non-root users on this machine.
Warning: the running version of Bundler is older than the version that created the lockfile. We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.
You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated ../Gemfile.lock to version control.

If this is a development machine, remove the /opt/redmine-4.0.4-1/apps/redmine/htdocs/Gemfile freeze
by running `bundle install --no-deployment`.
