按照http://rubygems.org/gems/mobile-fu上的说明安装 gem （“只需添加gem 'mobile-fu'到您的 Gemfile 并运行 bundle install”）工作正常，并且 gem 被列为已安装并且所有需要的依赖项也在放置AFAIK，下面是项目Gemfile的相关部分：

source :gemcutter
source 'http://gems.github.com'

gem 'rails', '~> 2.3.14'
gem 'aslakjo-comatose', '2.0.5.12', :require => 'comatose'
gem 'adamwiggins-rest-client', '1.0.4'
gem 'ruby-hmac', '0.4', :require => 'hmac'
gem 'ruby-net-ldap', '0.0.4', :require => 'net/ldap'
gem 'will_paginate', '2.3.11'
gem 'hpricot', '0.8.2'
gem 'oauth', '0.3.6'
gem 'sanitize', '1.1.0'
gem 'sunspot_rails', '1.1.0', :require => 'sunspot/rails'
gem 'htmlentities'
gem 'rdoc', :require => 'rdoc'
gem 'to_xls'
gem 'pusher'
gem 'jammit'
gem 'rabl', '~>0.6'
gem 'paperclip', '~> 2.7'
gem 'aws-sdk', '~> 1.3.4'
gem 'mobile-fu', '~> 1.1.0'
...

这是启动服务器时产生的错误消息/日志：“没有要加载的此类文件--mobile / fu（MissingSourceFile）”是主要问题（恕我直言）：

使用 Ben Langfeld 描述的解决方案（“您可以在 Gemfile 中使用以下内容解决此问题：gem 'mobile-fu', '~> 1.1.0', :require => 'mobile-fu'”）只会产生如下所示的新错误：

没有为此 gem 列出的 ruby​​ 或 rails 的最低版本，但我怀疑问题是由我们正在运行的旧版本引起的。但是，升级 ruby​​ 或 rails 不是一种选择，因为这是一个维护项目。

如果存在任何已知可在我们的 ruby​​ 和 rails 版本/配置上运行的具有类似功能的 Mobile Fu 替代 gem，如果无法解决此问题，我们愿意研究该替代选项。

您可以在 Gemfile 中使用以下内容解决此问题：

gem 'mobile-fu', '~> 1.1.0', :require => 'mobile-fu'

由于 Mobile Fu gem 与 ruby​​ 1.8.x / rails 2.3.x 不兼容，我们最终根据以下文章创建了自己的类似功能：http: //erniemiller.org/2011/01/05/mobile-devices -and-rails-maintaining-your-sanity/
