平台：Fedora 16
Rails 3
Formtastic 2
我正在尝试安装https://github.com/kristianmandrup/formtastic_datepicker-rails3x
将Gem文件包含在Gemfile中
gem 'formtastic_datepicker-rails3x', :git => 'git://github.com/kristianmandrup/formtastic_datepicker-rails3x.git'
我试过脚手架作为
rails g scaffold due_date date:date
我收到了错误

我搜索了其他相关问题，但他们都涉及从Ruby 2迁移到3或erb vs eruby。
