手机福宝不工作在红宝石1.8.7 /轨2.3.14

Question

按照http://rubygems.org/gems/mobile-fu（“简单地将添加到您的Gemfile和运行捆绑安装”）的说明安装宝石工作正常，并且该宝石被列为已安装和所有必要的依赖也已到位据我所知，下面是项目Gemfile中的相关部分：

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' 
... 

这里是导致错误消息/启动服务器时记录：“没有这样的文件来加载 - 移动/ fu（MissingSourceFile）“是主要问题（恕我直言）：

使用本Langfeld描述的解决方案（“为此，可以使用在你的Gemfile以下修正：gem 'mobile-fu', '~> 1.1.0', :require => 'mobile-fu'”）只产生一个新的错误如下图所示：

有没有列出这个宝石的最低版本的红宝石或铁轨，但我怀疑问题是由我们正在运行的旧版本引起的。但是，升级红宝石或导轨不是一种选择，因为这是一个维护项目。

如果存在已知可用于我们的ruby & rails version/config的具有类似功能的Mobile Fu的替换宝石，那么我们愿意查看这个问题是否可以解决。

Answer 1

为此，可以使用修复您的Gemfile如下：

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

Answer 2

因为移动富宝石不使用Ruby 1.8.x的兼容/导轨2.3.x版本中，我们结束了创建我们自己的类似功能的基于在下面的文章：http://erniemiller.org/2011/01/05/mobile-devices-and-rails-maintaining-your-sanity/
