“Rack::RawUpload”的未定义方法“新”：字符串

Question

我在 gem 文件中使用gem 'rich', GitHub: 'bastiaanterhorst/rich'， 在我运行 rails generate rich:install 时运行 bundle install 后 我遇到了这个错误

我没有得到解决方案

> undefined method `new' for "Rack::RawUpload":String

不过我也试过 gem 'rack-raw-upload', :git => 'git://github.com/tb/rack-raw-upload.git' 但仍然出现同样的错误。
