如何在 ruby​​ on Rails 3 中使用 USPS API 中的 Shipping gem？

Question

我在这里找到了 ruby​​ 的 shipping gem http://shipping.rubyforge.org/< /a> 在 google 上搜索有关在 Ruby on Rails 应用程序上集成 USPS API 的一些信息，但是当我安装 gem 并将其添加到我的 Gemfile 时，我运行 <代码>捆绑每当尝试运行我的应用程序或 rake 任务时安装 都会收到以下错误：

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

我现在已从我的 Gemfile 中删除了 gem，并且我的应用程序已启动并正在运行，但是，我不'甚至不知道这个 gem 是否适用于 Rails 3 或者即使这个 gem 适用于 USPS API。

对此有什么帮助吗？我需要将 USPS Web 工具与我的 Ruby on Rails 3 应用程序集成。

谢谢。
