为什么我的heroku应用程序依赖于will_paginate gem，这不再出现在我的gemfile中了？
您好，
我在Heroku上运行了一个rails 3.2.11应用程序。自从我上次成功部署到Heroku后，我就在本地：
本地应用程序运行正常。
当我将此应用程序（从git）部署到heroku时，我在日志中得到以下异常：

似乎我在Heroku上的应用程序仍然需要will_paginate gem。我怎样才能找出原因？
我尝试将此应用程序部署到一个新的heroku应用程序，基本上应该只使用我的Git中的代码而不是引用一些以前部署的代码/配置，但结果是相同的。
这是我的Gemfile：
source 'https://rubygems.org'
gem 'rails', '3.2.11'
# REPLACED BY KAMINARI gem: gem 'will_paginate' #, "~> 2.3.11", :source => 'http://gemcutter.org'
gem 'kaminari'
gem 'meta_search', "~> 1.1.3"
gem 'hirb', "0.5.0"
gem "paperclip", "~> 3.0"
gem 'i18n'
gem 'rake', '10.0.3'
# needed for amazon s3
gem 'aws-sdk'
# needed for mysql (cleardb mysql on heroku)
gem 'activerecord-mysql-adapter'
gem 'mysql2'
group :development, :test do
end
group :production do
gem 'pg'
# for heroku production
gem 'thin'
gem 'rails_12factor'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
# to be able to test thin locally
gem 'foreman'
gem "hirb", "0.5.0"
gem 'factory_girl'
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'debugger'

/config/initializers/中有一个剩余的初始值设定项引用了will_paginate。
