Redmine

Попытка установить плагин Redhopper на Debian 10 + Bitnami Redmine (https://www.redmine.org/plugins/redhopper) заканчивается сообщением:

Could not find gem 'acts_as_list (~> 0.9.17)' in any of the gem sources listed in your Gemfile.
Run `bundle install` to install missing gems.

Выполнение bundle install (как зашитого в сборку, так и системного) так:

1. bundle install
   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
