我是Ruby on Rails的新手,我一直在尝试在过去的三天里将一个带有Ruby on Rails 的简单Cappuccino应用程序部署到Heroku上,每次初始化(heroku rake db:migrate)时我都会遇到以下错误.

(in /app)
rake aborted!
uninitialized constant Rake::FileUtilsExt
/usr/ruby1.9.2/lib/ruby/1.9.1/rake.rb:2482:in `const_missing'
/app/Rakefile:15:in `<module:RakeFileUtils>'

我已经更新了所有必需的宝石和包.这是我的宝石列表供您参考:

*** LOCAL GEMS ***

abstract (1.0.0)
actionmailer (3.0.9, 3.0.8, 3.0.7, 3.0.5)
actionpack (3.0.9, 3.0.8, 3.0.7, 3.0.5, 2.3.8)
activemodel (3.0.9, 3.0.8, 3.0.7, 3.0.5)
activerecord (3.0.9, 3.0.8, 3.0.7, 3.0.5)
activeresource (3.0.9, 3.0.8, 3.0.7, 3.0.5)
activesupport (3.0.9, 3.0.8, 3.0.7, 3.0.5, …

我已经使用Mongoid,Devise和Omniauth为Facebook登录构建了一个基本的Rails应用程序.我在本地运行它没有问题,但是当我尝试推送到Heroku时,我收到了这个错误:

"/app/app/controllers/Users/omniauth_callbacks_controller.rb:1:in `': uninitialized     constant Users (NameError)"

我用一点运气用谷歌搜索出了这个地狱.我已经提交了User模型,我已经运行了"heroku run rake db:migrate"等等.没有运气.这是我的堆栈.
