我有2个月的问题了，我在无数线程中遇到的关于此问题的答案都没有解决我的问题。因此，我尝试了另一种令人沮丧的尝试：
这是我的应用在Heroku上的生产环境中运行时遇到的JavaScript错误。
我在浏览器控制台中看到的错误是：
Uncaught TypeError: ht.each is not a function
at application-b030a52a6989f6564d19974180747e99f4ac5a28109188d096b47fc12a38f2cf.js:1

当我在本地生产环境中运行我的App时，没有出现此错误，这是因为我的

有人可以帮我在Heroku上运行它吗？
有问题的代码是迈克尔·哈特尔（Michael Hartl）一对一编写代码的标准“ sample_app”，它或多或少适用于其他所有人，但不适用于我。
我正在使用最新的Rails和Ruby在Windows上工作
我尝试过的事情：
＃1：：预编译public / assets文件夹并清理然后推送，这当然很愚蠢，因为git不会推送此文件夹，但是人们建议我遵循
＃2：删除上面的文件夹，然后将其推送，再次出现与上面相同的问题...
＃3：以各种可能的方式在我的app/assets/javascripts/application.js文件中重新排列require语句 ：
//= require jquery
//= require bootstrap
//= require rails-ujs
//= require turbolinks
//= require_tree .
4 ：当其他人搜索“ Heroku Javascript错误”，“ Heroku Rails javascript生产中的错误”，“ Heroku rails的DELETE方法在生产中不起作用”，还有很多，正如我所说的，我已经在寻找解决方案已有2个月了，Ive在经过2,3个小时毫无结果的搜索后有足够的时间尝试放弃。 / p>
