基本上，我更新了我的config/environments/production.rb文件，然后按了
这个建议https://devcenter.heroku.com/articles/rails-asset-pipeline#compiling-assets-locally，但它仍然无效。
# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
# config.assets.precompile += %w( search.js ) # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
config.assets.precompile += %w( home.css )
然后执行以下操作：
~/collegeanswerz >> RAILS_ENV=production bundle exec rake assets:precompile

但我仍然遇到同样的500错误。
任何人都可以帮我这个吗？我急于部署，我无法弄清楚我做错了什么。我通读了https://devcenter.heroku.com/articles/rails-asset-pipeline#compiling-assets-locally和http://guides.rubyonrails.org/asset_pipeline.html，但我仍然不知道出了什么问题。任何帮助，将不胜感激。感谢。
编辑：我只将home.css添加到config/environments/production.rb。我有其他css文件和javascript文件。我需要将它们与home.css一起添加吗？我很困惑我需要添加到这个文件和我不需要的东西。

现在，我看到你的日志，我做了一些环顾四周，你不是唯一一个体验这个的人。尝试删除本地编译的资产：git rm -r public/assets然后推送到heroku。将您所做的更改保留在production.rb。
答案 1 :(得分：0)
我在StackOverflow中看到了你的帖子，很酷！我喜欢看到人们在社区中互相帮助。 你还记得上次造成问题的原因吗？那是：
ActionView :: Template :: Error（home.css未预编译）： 您需要将home.css添加到config / environments / production.rb。你需要告诉production.rb你需要home.css。您需要告诉您需要其他css文件而不是application.css。
现在，您在部署后在日志中看到了什么错误？
ActionView :: Template :: Error（layout.css未预编译）： 算了？现在您还需要添加layout.css。您可以像这样添加：
％w（home.css layout.css） 同样，您需要将除application.css之外的所有css添加到config / environments / production.rb。如果你有一些js文件，你需要添加除application.js以外的其他文件，你还需要添加到config / environments / production.rb。我可以看到你需要在你的应用程序中添加很多css文件（例如，college_pages，essays，about_college等用于css，about_college用于js）。 读取日志是调试和编程的第一步。日志总是告诉你一些事情（如果没有日志，我就无法指出你的问题！）。对不起，我没告诉你如何看日志（好像你不知道）。
以下是阅读日志的用法：
用法：heroku日志
显示最近的日志输出
-n， - num NUM＃要显示的行数 -p， - ps PS＃仅显示给定进程的日志 -s， - source SOURCE＃仅显示来自给定源的日志 -t， - tail＃不断传输日志
示例：
$ heroku日志 2012-01-01T12：00：00 + 00:00 heroku [api]：通过email@example.com配置添加示例 2012-01-01T12：00：01 + 00:00 heroku [api]：发布v1由email@example.com创建 您可以执行类似heroku logs -n 100之类的操作来查看最近100行日志。
希望这有帮助， 惠子
非常感谢你的帮助！我知道你有点超越自己的责任，我很感激。
我将所有其他css和js文件添加到production.rb并成功部署！我感到困惑的原因是我没有意识到我必须将所有这些都包含在production.rb中。我认为由于某种原因，application.css和application.js以某种方式使它成为我所没有的，并且我认为home.css由于某种原因是一个例外。
