如果gem源指定为git，则ActiveMerchant ActionView助手初始化会崩溃，但如果它是默认路径或本地路径，则可以工作。

Question

我有一个奇怪的bug，这取决于我如何在Gemfile中指定gem。

如果我使用标准宝石作为

gem 'activemerchant'

或者从路径加载它，如

gem 'activemerchant', path: '/home/alexd/src/active_merchant'

但是，如果我从git加载它，如

gem 'activemerchant', git: 'https://github.com/Shopify/active_merchant'

然后，下面的代码会导致运行rspec时崩溃。

config/initializers/active_merchant.rb

ActionView::Base.send(:include, ActiveMerchant::Billing::Integrations::ActionViewHelper)

更新

在config/initializers/active_merchant.rb中，甚至可以通过简单的要求触发崩溃。

require 'active_merchant/billing/integrations/action_view_helper.rb'

看起来是由路径长度引起的。如果我需要具有较短路径名的模块，它可以工作：

require 'active_merchant/billing/integrations/moneybookers.rb'

崩溃也是由路径跟踪时间较长的任何模块崩溃造成的。

require 'active_merchant/billing/integrations/paypal_payments_advanced.rb

我认为创业板的网址必须是git://github.com/username/repo_name .git格式

因此，对于你的例子：

gem 'activemerchant', :git => 'git://github.com/Shopify/active_merchant.git'

来自http://bundler.io/v1.3/man/gemfile.5.html

如果有必要，可以指定gem位于特定的GIT存储库中。存储库可以是公共存储库(http://github.com/rails/rails.git)，也可以是私有存储库(git@github.com:rails/rails.git)。如果存储库是私有的，用于运行bundle安装的用户必须在其$HOME/..ssh中拥有可用的相应密钥。 Git存储库使用:git参数指定。组、平台和require选项是可用的，它们的行为与正常的gem完全相同。 gem "rails"，:git => "git://github.com/rails/rails.git“

这在我的Rails 3.2.16应用程序中适用于我。

或者，您可以使用:github的缩写来表示公共回购：

GITHUB ( :github )如果您想要使用的git存储库是托管在GitHub上并且是公共的，您可以使用: github简写来指定github用户名和存储库名(没有尾随的".git")，用斜杠分隔。如果用户名和存储库名称都是相同的，则可以省略一个。 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ruby2.x解决了这个问题，但我仍然在寻找适用于1.9.3的解决方案，因为我还没有准备好将整个应用程序迁移到ruby2.x。
