Rails 5生产应用程序中的Heroku JS错误
我现在有两个月的问题，我在这个问题的无数线索中得到的答案都没有解决我的问题。 所以我给它另一个令人沮丧的尝试：
当我的应用程序在Heroku上运行时，我得到了一个JavaScript错误。
我在浏览器控制台中获得的错误是：
Uncaught TypeError: ht.each is not a function at application-b030a52a6989f6564d19974180747e99f4ac5a28109188d096b47fc12a38f2cf.js:1 at application-b030a52a6989f6564d19974180747e99f4ac5a28109188d096b47fc12a38f2cf.js:1 at application-b030a52a6989f6564d19974180747e99f4ac5a28109188d096b47fc12a38f2cf.js:1 当我在本地生产我的应用程序时，我不会收到此错误，这是因为我的

文件夹看起来像这样：
.sprockets-manifest-a7e0d8d7f0627b40ca52eea9623fee45.json application-a358e1eb31a8f590691be18692bb2f57be910bbb2c5800a4dcb95a6c56deb358.js application-a358e1eb31a8f590691be18692bb2f57be910bbb2c5800a4dcb95a6c56deb358.js.gz application-ea2c1b8977f914f6ea0d3aa17e9a18079d0fd8ab6b9aa1a88609bcaba62135d5.css application-ea2c1b8977f914f6ea0d3aa17e9a18079d0fd8ab6b9aa1a88609bcaba62135d5.css.gz bootstrap rails-c094bc3a4bf50e5bb477109e5cb0d213af27ad75b481c4df249f50974dbeefe6.png
在Heroku上，同一个文件夹包含以下内容：

在本地，这些JavaScript文件被加载到发生错误的站点：
但是在Heroku上，该站点只加载了这个JS文件 （它似乎是由本地加载的所有文件组成的，现在互相冲突，但我真的不知道）
有人可以帮我把它运行在Heroku上吗？
有问题的代码是Michael Hartl的标准“sample_app”，他的代码是1对1，它或多或少地适用于其他所有人，但不适合我。
我正在Windows上使用Rails和Ruby更新
我试过的：
＃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没有推送这个文件夹，但人们建议我跟着
＃2：删除上面的文件夹然后再推它，同样的问题就像上面那样……
＃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：当搜索诸如“Heroku Javascript错误”，“Heroku rails javascript生产中的错误”，“Heroku rails DELETE方法在生产中不起作用”之类的东西时，更多的“解决方案”对其他人很有用，这些解决方案在堆栈溢出时很容易找到更多，正如我所说，我现在正在寻找解决方案2个月，我已经有足够的时间尝试放弃2,3小时无结果搜索。

这是uglifiergem。 我从4.1.18降级到3.0.4
