多年来人们都有这个问题。我尝试了一些答案的组合，但我仍然无法在我的Rails 5.1.6应用程序中获取更新的样式表和javascript以加载Heroku。它适用于我的本地机器。
这是我的文件。
应用程序/资产/样式表/ application.scss
*= require_tree .
*= require_self
应用程序/视图/布局/ application.html.erb
<html>
<head>
......
<%= stylesheet_link_tag "application", media: "all" %>
<%= csrf_meta_tags %>
<%= favicon_link_tag "/favicon.ico" %>
<%= render 'layouts/shim' %>
</head>
<body>
......
<%= debug(params) if Rails.env.development? %>
<%= javascript_include_tag "application" %>
</body>
</html>
配置/ application.rb中

这是我在本地机器上所做的。
rake assets:clean
rake assets:precompile
rake assets:precompile RAILS_ENV=production
committed changes with public/assets folder included using Github desktop app
git push heroku master
git push heroku master -f when initial change did not work after adding spaces to a file to avoid everything-up-to-date message.
heroku rake assets:precompile RAILS_ENV=production
heroku restart several times along the way
heroku repo:clone -a myapp to verify that my app/assets folder was up to date
heroku repo:reset -a myapp to empty the heroku repo
git push heroku master
heroku logs -t
我已经多次清除浏览器中的缓存，重新启动计算机并在不同的设备上显示新的应用程序。我在heroku日志中看到没有错误。我的css和js无法正常工作。还有什么地方可以解决这个问题？
我检查了你的配置文件，在config/environments/production.rb你有config.serve_static_assets = true的错误;因此，您需要更改为config.public_file_server.enabled = true，并且还请更改config.assets.compile = false，因为我认为您不想在每个请求中编译资产。
这是类似的用法：config/environments/production.rb
