【问题描述】：

我是 twitter API 和 MongoDb 的新手。我正在尝试“MongoDb In Action”一书中的一个 ruby 示例，第 3 章连接到 Twitter 并根据给定的标签获取提要。我已经按照建议完成了红宝石设置。我收到以下异常，我认为这与 ruby 设置有关。任何提示都非常感谢。

您正在阅读的这本书是 2011 年印刷的，并且似乎使用了最近被 twitter 贬值的 APIv1。

https://dev.twitter.com/docs/faq#17750

您需要设置 oauth，我建议您从 twitter gem 文档开始。

非常感谢。根据您的指示，我找出了所需的更改，并且现在正在运行。
