我试图在16.04 ubuntu的机器上安装redmine的插件。现在我正在尝试安装敏捷插件。我收到了有关如何安装插件的官方文档。我按照一步一步的安装，我遇到了错误。
重要提示：
我使用的是Ruby 2.3.1。
步骤
cd /var/www/redmine和bundle install --without development test --no-deployment
（由于mysql，nokogiri和其他宝石，我在这里遇到了一些错误..但现在一切都好了）bundle exec rake redmine:plugins NAME=redmine_agile RAILS_ENV=production 但是每次执行上一个命令时都会收到此错误：
（在/ usr / share / redmine中）rake中止了！ NameError：未初始化 常量ActionDispatch :: XmlParamsParser您的意思是？ ActionDispatch :: ParamsParser
这是完整的日志:(带跟踪）

我看到其他帖子，我已经尝试过了：
更改版本：我有最后一个redmine版本
gem install actionpack-xml_parser
更新Bundler
在redmine root上执行rake（我在/ var / www / html / redmine上执行
我在redmine仪表板上看到一些帖子来修复这个错误..它回到了2015年..我希望现在有一些修复
结构
我在 / var / www / html / redmine 上安装了我的redmine，并在 / var / www / html / redmine / plugins 上安装了我的插件。我在 / var / www / html / redmine 上执行我的命令。
