我有一个 Dashing 仪表板，并希望在其中使用 Dashing EC2 Cloudfront 小部件。小部件的要点在这里https://gist.github.com/jwalton/6614087和 Dashing 在这里http://shopify.github.io/dashing/#widgets
我让 RVM 管理我的 ruby 和 gems，并安装了 aws-sdk gem 以及所有其他 gem。
#lib/dashing_ec2.rb 文件导致需要 aws-sdk 的错误
当我研究 Backports 并没有发现任何相关的东西时，我不确定从这里该怎么做。
这是来自 Dashing 的 thin.log 的错误：
