我正在尝试安装“ERPmine”插件：
官方文件：http://www.redmine.org/plugins/wk-time
正如文档所说，并且像我以前用过的每个插件一样：
importing this plugin to the /redmine/plugins directory
(successfull)
running: bundle install (successfull)
Redmine 3.4.2.stable
Attachments directory writable
Plugin assets directory writable (./public/plugin_assets)
RMagick available (optional)
ImageMagick convert available (optional)
Environment:
Redmine version 3.4.2.stable
Ruby version 2.3.1-p112 (2016-04-26) [x86_64-linux-gnu]
Rails version 4.2.8
Environment production
Database adapter Mysql2
SCM:
Git 2.7.4
当我对此表示赞扬时：
rake db:migrate RAILS_ENV=production
