Rails 5生产应用程序中的Heroku JS错误 [英] Heroku JS error in Rails 5 production app
本文介绍了Rails 5生产应用程序中的Heroku JS错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我现在有两个月的问题，我在这个问题的无数线索中找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，我得到一个JavaScript错误。
我在浏览器控制台中遇到的错误是：
未捕获的TypeError ：ht.each不是函数
。在应用b030a52a6989f6564d19974180747e99f4ac5a28109188d096b47fc12a38f2cf.js：1个

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
/ public / assets
文件夹如下所示：

有人可以帮助我让它在Heroku上运行吗？
有问题的代码是迈克尔·哈特尔（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。
我在Windows上使用Rails和Ruby最新
我尝试过：
＃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没有推送此文件夹，但人们建议我按照
＃2：删除上面的文件夹，然后推送它，再次像上面一样的问题......
＃3：以可能的方式重新排列 app / assets / javascripts / application.js 文件中的require语句 ：
// = require jquery
// = require bootstrap
// = require rails-ujs
// =需要turbolinks
// = requ ire_tree。
4：更多适用于其他人的解决方案当一个人搜索Heroku Javascript错误，生产中的Heroku rails javascript错误，Heroku rails DELETE方法在生产中无法正常工作以及更多内容时，可以找到堆栈溢出，正如我所说我正在寻找解决方案已经有2个月了，我已经有足够的时间尝试放弃2,3小时无效的搜索。

解决方案
这是 uglifier gem。我将 4.1.18 降级为 3.0.4
I have an issues for 2 months now and none of the answers that I got here in my countless threads about this issue have resolved my problem. So I give it another frustrating try:
It is a JavaScript error that I get when my App runs in production on Heroku.
The Error that I get in the Browser Console is this:
Uncaught TypeError: ht.each is not a function
at application-b030a52a6989f6564d19974180747e99f4ac5a28109188d096b47fc12a38f2cf.js:1

When I run my App in production locally I dont get this error, this is because my
/public/assets
folder looks like this:

can someone please help me to get it running on Heroku?
The code in question is the standard "sample_app" by Michael Hartl doing his code 1-to-1 and it works for everyone else more or less but not for me.
I am working on Windows with Rails and Ruby up-to-date
What I have tried:
#1: precompiling the public/assets folder and cleaning up then pushing, which is of course silly because git doesnt push this folder but people suggested I followed
#2: deleting the folder above and then push it, again same problem like above...
#3: rearranging the require statements in my app/assets/javascripts/application.js file in every possible way:
//= require jquery
//= require bootstrap
//= require rails-ujs
//= require turbolinks
//= require_tree .
4: many more "solutions" that worked for others which are easily findable on stack overflow when one searches for things like "Heroku Javascript error", "Heroku rails javascript error in production", "Heroku rails DELETE method doesnt work in production" and many more, as I said I am on the search for a solution for 2 months now allready, Ive had plenty of time to try and give up after 2,3 hours of fruitless search.
