我有一个奇怪的错误，这取决于我如何在Gemfile中指定gem。
如果我使用标准宝石作为，没有问题
gem 'activemerchant'
或从中的路径加载
gem 'activemerchant', path: '/home/alexd/src/active_merchant'
但是如果我像在中那样从git加载
gem 'activemerchant', git: 'https://github.com/Shopify/active_merchant'
则以下代码导致运行rspec 时崩溃
config/ininitializers/active_merchant.rb:
ActionView::Base.send(:include, ActiveMerchant::Billing::Integrations::ActionViewHelper)

更新
崩溃甚至可以通过config/iinitializers/active_merchant.rb:中的简单需求触发
require 'active_merchant/billing/integrations/action_view_helper.rb'
并且看起来是由路径长度引起的。如果我需要路径名更短的模块，它可以工作：
require 'active_merchant/billing/integrations/moneybookers.rb'
崩溃也由路径名较长的任何模块引起-以下崩溃也是
require 'active_merchant/billing/integrations/paypal_payments_advanced.rb
我认为gem的URL必须采用git://github.com/username/report_name格式.git
举个例子：
gem 'activemerchant', :git => 'git://github.com/Shopify/active_merchant.git'
发件人http://bundler.io/v1.3/man/gemfile.5.html
GIT（：GIT）如果需要，可以指定gem位于特定的git存储库。存储库可以是公共的(http://github.com/rails/rails.git)或私人(git@github.com：rails/rails.git）。如果存储库是私有的，则用于运行捆绑包安装的用户必须具有相应的密钥在他们的$HOME/.ssh.中提供
Git存储库是使用：Git参数指定的。该组，平台，和require选项可用，并且行为完全符合就像普通宝石一样。
gem"rails"，：git=>"git://github.com/rails/rails.git"
这在我的Rails 3.2.16应用程序中适用。
或者，看起来您可以使用:github来表示公共回购：
GITHUB（：GITHUB）如果要使用的git存储库托管在GitHub是公共的，您可以使用：GitHub简写来指定只有github用户名和存储库名称（没有尾部".git"），用斜线分隔。如果用户名和存储库名称相同，可以省略一个。
gem"rails"，：github=>"rails/rails"
gem"rails"，：github=>"rails"
两者都相当于
gem"rails"，：git=>"git://github.com/rails/rails.git"
升级到ruby 2.x解决了这个问题，但我仍在寻找适用于1.9.3的解决方案，因为我还没有准备好将整个应用程序移动到ruby 2.x.
