我正在尝试将 intercom.io 安装到我的 rails 应用程序中，但是在生成配置文件时我得到了这个：

/var/lib/gems/1.8/gems/intercom-rails-0.2.14/lib/intercom-rails/config.rb:13:in `send': undefined method `define_singleton_method' for IntercomRails::Config:Class (NoMethodError)

看起来您使用的是 ruby​​ 1.8，我们的 gem 当前使用 ruby​​ 1.9 功能Object#define_singleton_method

我们在intercom/intercom-rails github repo上创建了一个问题来跟踪修复此问题。有新版本时我会通知你的。

如果可能，建议在 ruby​​ >= 1.9.3 上运行 rails 3+（这对我们来说至少意味着不从源代码安装）。

谢谢让我们注意到这个。
