ruby-on-rails - 当我的Rails 3.2.0应用程序处于开发模式时，为什么不能编译对coffeescript文件的更改？

Question

通常，在刷新页面时，在开发模式下对Rails 3.2.0应用程序中的.js.coffee文件所做的任何更改都会生效。突然之间，这没有发生。如果我执行rake assets:precompile，则将显示更改，但是如果我执行rake assets:clean，它们将返回至未显示。是什么原因造成的？

编辑：重新启动服务器将显示更改。为什么这没有像以前那样自动发生？

编辑：这是我的development.rb

Myapp::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Log error messages when you accidentally call methods on nil.
  config.whiny_nils = true

  # Show full error reports and disable caching
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger
  config.active_support.deprecation = :log

  # Only use best-standards-support built into browsers
  config.action_dispatch.best_standards_support = :builtin

  # Raise exception on mass assignment protection for Active Record models
  config.active_record.mass_assignment_sanitizer = :strict

  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  config.active_record.auto_explain_threshold_in_seconds = 0.5

  # Do not compress assets
  config.assets.compress = false

  # Expands the lines which load the assets
  config.assets.debug = true
  config.action_mailer.default_url_options = { :host => 'localhost:3000' }

  config.log_level = :warn


end

我是Rails的新手（嗯...我只学习了不到3个月的编程知识

我猜：

您或某些安装更改了config / application.rb中的配置

您可以检入文件：

config.assets.initialize_on_precompile是false吗？

更改为true，然后重试。

还要检查config.assets.compile。是true吗？

您可以在Rails 3.2中更改默认值。因此，我建议您考虑一下为什么会发生更改。
