我在shipping这里找到了 ruby​​ 的 gem http://shipping.rubyforge.org/在 google 上搜索有关在 USPSRuby on rails 应用程序上集成 API 的一些信息，但是当我安装 gem 并将它添加到Gemfile我bundle install时尝试运行我的应用程序或 rake taks 我收到以下错误：

我现在已经从我的应用程序中删除了 gem，Gemfile并且我的应用程序已经启动并正在运行，但是，我什至不知道这个 gem 是否适用于Rails 3或者即使这个 gem 是否适用于USPSAPI。

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。

运输 gem 很旧，不能与 rails 3 一起使用（最后一次发布是 2009 年10 月）

试试https://github.com/Shopify/active_shipping

它支持：

  • UPS
  • 美国邮政总局
  • 联邦快递
  • 加拿大邮政
  • 新西兰邮政
