我在 Codepen 上创建了一个页面，稍后将添加到我的 Ruby on Rails 应用程序( https://codepen.io/salman15/pen/evQVLV )，所有代码都可以正常工作。
创建页面后，我尝试使用 spree 将页面添加到我的 Ruby on Rails 应用程序(它在 Cloud 9 上运行 https://consulegem-salman15.c9users.io/ “您阅读本文时服务器可能未离线”)。我通过以下方式完成了此操作:
第 1 步:将 html 代码添加到 index.html.erb
第 2 步:将 CSS CDN 添加到 _head.html.erb
第 3 步:下载所有 JavaScript 库并将它们添加到以下文件夹路径 -> app -> assets -> javascripts -> frontend -> store
第 4 步:将以下代码行添加到我的 all.js 文件(在前端文件夹中)
//= require_tree
此时我的代码应该可以正常工作，但它没有。

令我烦恼的是，完全相同的代码和完全相同的库似乎无法在我的 Ruby on Rails 应用程序上运行，这就是我的幻觉，为什么？
is not a function错误是因为代码无法识别，通常是因为库没有加载。然而，我在加载页面并加载所有库后检查了源页面。
TweenMax 错误也是我的幻影，因为它是相同的库和相同的代码。
我已经尝试了几种解决方案，比如将库代码添加到我的 script.js 中，它似乎可以工作，但这是一个不合适的解决方案。
我想我已经准备好了所有需要的信息和代码，但如果您还需要，请随时询问。
总结一下我的问题:
问题:我的 Jquery 库似乎不起作用
问题:为什么？

回答
您可以在下面的答案中找到答案，但这不是答案的唯一部分。答案的最后一部分在 CSS 中，我的 body 发生冲突导致部分错误。因此，如果您遇到同样的问题，请确保您的库加载到正确的位置(对我来说是底部)和正确的顺序。还要确保您的 CSS 也不会导致任何错误。
最佳答案
根据您粘贴的文件，库的加载顺序错误。我怀疑应将以下行移至您的 application.js 的末尾 list ，以确保它仅在所有 jQuery 之后加载插件是。像这样的东西:
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .
请注意，require_tree不保证自定义脚本的加载顺序。因此，如果一个脚本依赖于另一个脚本，您仍然会遇到这些问题。您应该尝试编写独立脚本，这样执行顺序就无关紧要了。如果您绝对必须编写相互依赖的脚本，那么您应该倾向于在 list 中以正确的顺序手动导入它们。
此外，您的导入看起来不对。您似乎已经三次导入 jQuery。您应该粘贴 <head> 的内容在开发模式下在最终呈现的页面中添加标记，以确保这确实有效。
//= require_jquery.min <-- second import!
//= require_jquery-3.2.1.min <-- third import!
//= require_jquery.easeScroll
//= require_jquery.logosDistort.min
//= require_jquery.particleground.min
//= require_jquery.jquery.scrollmagic.min
尝试:
//= require jquery.easeScroll
将相关 gem 添加到您的 Gemfile 后，当然。
