无法安装Intercom.io gem Ubuntu 12.04 LTS

Question

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)

Answer 1

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

我们在intercom / intercom-rails github存储库上创建了一个问题，以跟踪解决此问题。 有新版本时，我会通知您。

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

谢谢让我们注意到这个。
