按照http://rubygems.org/gems/mobile-fu上的说明安装gem（＆＃34;只需将gem 'mobile-fu'添加到您的Gemfile并运行bundle install＆＃34;）就可以了，并且gem已列为已安装且所有所需的依赖关系也到位AFAIK，下面是Gemfile项目的相关部分：

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：＆＃34;没有要加载的文件 - mobile / fu（MissingSourceFile）＆＃34;是主要问题（恕我直言）：

使用Ben Langfeld描述的解决方案（＆＃34;您可以使用Gemfile中的以下内容解决此问题：gem 'mobile-fu', '~> 1.1.0', :require => 'mobile-fu'＆＃34;）仅产生如下所示的新错误：

此gem没有列出最低版本的ruby或rails，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。

如果存在具有类似功能的Mobile Fu的替代宝石，则可以使用我们的ruby＆amp; rails version / config，如果无法解决此问题，我们愿意考虑备用选项。

您可以使用Gemfile中的以下内容解决此问题：

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

答案 1 :(得分：0)

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我们自己的类似功能：http://erniemiller.org/2011/01/05/mobile-devices-and-rails-maintaining-your-sanity/
