Question

我跟随michael hartl的轨道教程并陷入了第11章，他在那里实现了图像的上传。将我的gemfile更新为

后

source 'https://rubygems.org'

gem 'rails', '4.2.4'
gem 'sqlite3'
gem 'sass-rails', '5.0.2'
gem 'uglifier', '2.5.3'
gem 'coffee-rails', '~> 4.1.0'
gem 'bootstrap-sass', '3.2.0.0'
gem 'bcrypt', '3.1.7'
gem 'faker', '1.4.2'
gem 'carrierwave',             '0.10.0'
gem 'mini_magick',             '3.8.0'
gem 'fog',                     '1.26.0'
gem 'will_paginate', '3.0.7'
gem 'bootstrap-will_paginate', '0.0.10'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks', '2.3.0'
gem 'jbuilder', '~> 2.2.3'
gem 'sdoc', '~> 0.4.0', group: :doc

group :development, :test do
  gem 'byebug', '3.4.0'
end

group :development do
  gem 'web-console', '~> 2.0'
  gem 'spring'
end

group :test do
    gem 'minitest-reporters', '1.0.5'
    gem 'mini_backtrace',     '0.1.3'
  gem 'guard-minitest',     '2.3.1'
end

我运行了捆绑包并安装了宝石而没有遇到任何麻烦。但是当我试图运行时

rails generate uploader Picture

我收到以下消息：

到目前为止，我已尝试更改gem的版本，并运行捆绑更新，但没有任何效果。我甚至尝试使用git回滚我的应用程序再次尝试，但没有效果。

这里的任何人都知道发生了什么以及如何解决这个问题？
