所以我回过头来看看使用THIS question的答案的其他解决方案，它基本上告诉我这是一个与coffeescript不兼容的ES6错误问题，所以我在我的gemfile中添加了一个gem从最新版本的链轮解决问题，但它没有工作...我已经运行捆绑安装并重新启动我的应用程序，看看是否有任何帮助，到目前为止，我不知所措。我刚刚开始使用Ruby，而且我现在还不确定该怎么做。
为了让您知道我在做什么，我试图将elevateZoom jquery添加到普通文件中，这是从他们的github存储库开始的所有这些（jquery.elevateZoom-3.0.8.min.js） 。
如果你想查看我的github代码，它就在这里。我非常感谢任何人的帮助！ https://github.com/ggricius/TestApp

所以我已经解决了我自己的问题（通常情况下），我想发布它以便其他人也可以从错误中吸取教训。我的代码的问题出在我从github获取的elevateZoom文件中。我没有看那段代码，看看它看起来有多么不同，因为我只是认为它是正确的 - 一旦我去检查它，结果证明它完全是错误的文件 - 所以只是提醒人们去检查文件并不认为他们的正确理所当然！
