localhost:3000 不会更新我的 css，或者在删除静态文件或关闭时根本不会加载
localhost:3000 will not update my css, or will not load at all when static files are deleted of switch off
自从我预编译要部署到 Heroku 的资产以来，我一直在努力处理我的 rails 项目。 css 不会更新，所以我按照其他类似条目的建议删除了静态文件。该应用程序将永远不会加载，它只会处于缓冲状态。我还尝试简单地将 config.serve_static_files 设置为 false。在 运行 清理资产后，我得到了相同的结果。我也试过 dscacheutil -flushcache，但没有效果。

请帮助我，我很难做这样的工作。谢谢
你试过了吗运行rake assets:precompile？
一些小知识给你：
rake assets:clean
摆脱所有预编译资产的更好方法是rake assets:clobber。
这会主动删除 /public/assets 文件夹中的文件和文件夹，让您摆脱任何可能遗留的预编译资产。
--
又一则琐事：
每当 运行ning rake assets:precompile, 运行 它带有一个 ENV var:
rake assets:precompile RAILS_ENV=production
这可确保使用 生产 环境中可用的数据和设置对文件进行预编译，从而为您提供最可靠的文件。
作为我自己的规则，我总是尝试确保动态加载本地资源。
这不需要您做任何更改（事实上，我实际上会删除您的 development.rb 文件中的 serve_static_files 行）。
这样做的原因是，如果您在开发中处理预编译资产，则每次要测试它们是否已更改时都必须重新编译它们，既耗时又不可靠。
Heroku 应该只需要对其 production 环境进行资产预编译。
I cannot even run that it seems
这表明您的应用或 Ruby 安装存在更深层次的问题。
您需要做几件事来确保这不是主要问题：
将所有 CSS 和 JS 删除到临时文件夹（如有必要，Recycle Bin），然后 运行 rake assets:precompile .可能有一个关闭 reference/loop 导致问题
使用 rails new TESTAPP 创建一个新的 Rails 应用程序，然后立即 运行 rake assets:precompile。如果运行良好，您就知道问题出在您当前的应用程序上
停止任何其他 运行ning 进程。如果您的程序 运行ning 可能会阻碍 cmd，它将顺利地阻止它 运行ning。
如果您使用 RubyInstaller 之类的方式安装您的 Ruby，您可能希望升级。如果没有，您可能仍希望升级。
最后，如果您的计算机处理 rake 命令的速度极慢，则表明存在重大系统问题。您需要确保它正常工作以确保顺利的开发周期。
