Ruby on rails 部署到Heroku时未在Rails 6应用程序中加载CSS和引导

我有一个Rails6项目，带有默认的webpacker。我按照教程加载了bootstrap和jQuery，一切都在本地运行。 以下是相关文件的结构：
app/javascript/packs/application.js

require("@rails/ujs").start()
require("turbolinks").start()
require("@rails/activestorage").start()
require("channels")
require('jquery')

#This file that is being imported handles importing in bootstrap and custom CSS files
import '../stylesheets/application'

@import "~bootstrap/scss/bootstrap";
#files below are custom css files
@import "reset";
@import "general";
@import "header";
@import "menu-overlay";

app/javascript/stylesheets/applications.scss

require("@rails/ujs").start()
require("turbolinks").start()
require("@rails/activestorage").start()
require("channels")
require('jquery')

#This file that is being imported handles importing in bootstrap and custom CSS files
import '../stylesheets/application'

@import "~bootstrap/scss/bootstrap";
#files below are custom css files
@import "reset";
@import "general";
@import "header";
@import "menu-overlay";

它在本地工作，但当我将其部署到Heroku时，引导样式和自定义css不会显示

我尝试过的事情
1） 我已经尝试运行rake资产：在本地预编译，然后再次部署它
2） 我已尝试在Heroku CLI中运行rake资产预编译：Heroku rake资产：预编译--应用程序暂存应用程序
3） 我已将这一行添加到我的environments/production.rb文件中

config.public\u file\u server.enabled=ENV['RAILS\u SERVE\u STATIC\u FILES']。是否存在？

我注意到，每当我在本地对资产进行任何更改时，控制台都会显示webpacker编译。。可能是Heroku没有运行我的webpacker编译

我是否必须在package.json文件中添加依赖项才能在生产中启动webpacker服务器

"dependencies": {
    "@rails/actioncable": "^6.0.0-alpha",
    "@rails/activestorage": "^6.0.0-alpha",
    "@rails/ujs": "^6.0.0-alpha",
    "@rails/webpacker": "^4.0.7",
    "bootstrap": "^4.3.1",
    "jquery": "^3.4.1",
    "popper.js": "^1.15.0",
    "turbolinks": "^5.2.0"
  },
  "version": "0.1.0",
  "devDependencies": {
    "webpack-dev-server": "^3.8.2"
  }

谢谢你的意见

至于控制台中的错误，没有错误。我运行了heroku日志——应用程序转移，没有错误。我还打开了检查器，没有错误

编辑3 我在包中添加了一个测试javascript文件，然后从application.js文件导入该文件：

require("@rails/ujs").start()
require("turbolinks").start()
require("@rails/activestorage").start()
require("channels")
require('jquery')

import './test.js'
import '../stylesheets/application'

---

在我的test.js文件中，我有一些输出到控制台的代码，它可以正常工作。如果css文件不起作用，我希望它不会起作用，但是javascript文件似乎起作用了

该死的。之所以没有在Heroku中加载它，是因为我在布局文件夹中的application.html文件中仍然使用了stylesheet\u link\u标记而不是stylesheet\u pack\u标记

因此，在本地开发中，由于有一个webpack dev服务器，它会编译它。但是，在heroku中，我必须指定它，如果我将样式表\u link\u标记改为使用样式表\u pack\u标记，我就可以这样做

 = stylesheet_pack_tag "application", media: 'all', 'data-turbolinks-track': 'reload'
 = javascript_pack_tag "application", 'data-turbolinks-track': 'reload'

---

我也遇到了同样的问题，通过保持样式表\u link\u标签的原样来解决，但添加了：

@import“bootstrap/scss/bootstrap.scss”

转到app/assets/stylesheets文件夹中的我的application.scss文件
 也有同样的问题！Heroku需要上述两种解决方案：

布局>application.html.erb

stylesheet_pack_tag "application", media: 'all', 'data-turbolinks-track': 'reload'

-及-

资产/样式表/application.scss

@import "bootstrap/scss/bootstrap.scss";

-或者-（主样式表存在的地方）

assets/javascript/stylesheets/application.scss

@import "bootstrap/scss/bootstrap.scss";

您会注意到，您的本地开发服务器将需要

当推到Heroku进行生产时，只需将其切换到

希望这能澄清：）
您在控制台中遇到了什么错误？您能粘贴Heroku部署输出吗？我得到了一些信息，比如
warn安装v1.16.0远程：[1/4]解析软件包。。。远程：[2/4]正在获取包。。。兼容性检查。将其从安装中排除。远程：[3/4]正在链接依赖项。。。远程：[4/4]正在生成新包。。。远程：在22.04秒内完成。远程：编译…远程：在/tmp/build_c088b78bcafdbababa7db163b4259759db/public/packs-remote中编译所有包：资产预编译已完成（29.93s）
@rockwelllice中似乎没有任何错误console@BSeven我已经在我的编辑1中附加了heroku部署输出，我已经在这个问题的圈子里了lol，只希望DHH从rails堆栈中删除链轮，这样我们就有了1个解决方案，而不是sprocket+webpacker，麻烦太多了。不幸的是，它没有加载我的scss文件。我仍然对它在本地开发中如何工作而在生产中如何不工作感到困惑？这对我来说很有用。简单易用。我不知道在什么情况下需要更复杂的解决方案。
