ImageScience:Class (NoMethodError) 的未定义方法“内联”

Question

我正在将 Rails 2.1.2 应用程序迁移到 Rails 2.3.11

为了让我的生活更轻松，我使用了 bundler，但在启动服务器时出现以下错误：

/Library/Ruby/Gems/1.8/gems/image_science-1.2.1/lib/image_science.rb:90: undefined method `inline' for ImageScience:Class (NoMethodError)
        from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/runtime.rb:64:in `require'

        from script/server:3

这有点奇怪，因为我在没有捆绑程序的情况下也能正常工作。我想我缺少 gem 依赖项。

宝石文件：

    gem 'mperham-deadlock_retry', :require => 'deadlock_retry'
    gem 'hoptoad_notifier', '2.4.2'
    gem 'will_paginate', '~> 2.3.15'
    gem "activemerchant", :require => "active_merchant"
    gem "newrelic_rpm"
    gem 'calendar_date_select'
    gem 'ckeditor', '3.4.3'     gem 'automatic_foreign_key'
    gem 'chronic'
    gem 'mechanize'
    gem 'rexml-expansion-fix'
    gem 'image_science', '1.2.1'
    gem 'inline', '0.1.0'
