Ruby rails在开发中模拟生产资产预编译，以解决css编译失败的问题

我正在试图找出为什么我的application.css.scss文件在我的登台环境中没有正确预编译。我已尝试在本地复制错误，方法是将本地环境文件替换为与登台文件相同的文件。在预编译之后（但不是预期的uglified），即使我正在为我的本地应用程序使用登台环境设置，所有的东西仍然可以在开发中工作

我的设置如下

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

  # Code is not reloaded between requests.
  config.cache_classes = true

  # Eager load code on boot. This eager loads most of Rails and
  # your application in memory, allowing both threaded web servers
  # and those relying on copy on write to perform better.
  # Rake tasks automatically ignore this option for performance.
  config.eager_load = true

  # Full error reports are disabled and caching is turned on.
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Enable Rack::Cache to put a simple HTTP cache in front of your application
  # Add `rack-cache` to your Gemfile before enabling this.
  # For large-scale production use, consider using a caching reverse proxy like nginx, varnish or squid.
  # config.action_dispatch.rack_cache = true

  # Disable Rails's static asset server (Apache or nginx will already do this).
  config.serve_static_assets = false

  # Compress JavaScripts and CSS.
  config.assets.js_compressor = :uglifier
  # config.assets.css_compressor = :sass

  # Do not fallback to assets pipeline if a precompiled asset is missed.
  config.assets.compile = false

  # Generate digests for assets URLs.
  config.assets.digest = true

  # `config.assets.precompile` has moved to config/initializers/assets.rb

  # Specifies the header that your server uses for sending files.
  # config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
  # config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx

  # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
  # config.force_ssl = true

  # Set to :debug to see everything in the log.
  config.log_level = :info

  # Prepend all log lines with the following tags.
  # config.log_tags = [ :subdomain, :uuid ]

  # Use a different logger for distributed setups.
  # config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)

  # Use a different cache store in production.
  # config.cache_store = :mem_cache_store

  # Enable serving of images, stylesheets, and JavaScripts from an asset server.
  # config.action_controller.asset_host = "http://assets.example.com"

  # Precompile additional assets.
  # application.js, application.css, and all non-JS/CSS in app/assets folder are already added.
  # config.assets.precompile += %w( search.js )

  # Ignore bad email addresses and do not raise email delivery errors.
  # Set this to true and configure the email server for immediate delivery to raise delivery errors.
  config.action_mailer.raise_delivery_errors = false
  config.action_mailer.default_url_options = { :host => '' }
  config.action_mailer.perform_deliveries = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    :address              => "smtp.gmail.com",
    :port                 => 587,
    :user_name            => '',
    :password             => '',
    :authentication       => 'plain',
  :enable_starttls_auto => true  }

  # Enable locale fallbacks for I18n (makes lookups for any locale fall back to
  # the I18n.default_locale when a translation cannot be found).
  config.i18n.fallbacks = true

  # Send deprecation notices to registered listeners.
  config.active_support.deprecation = :notify

  # Disable automatic flushing of the log to improve performance.
  # config.autoflush_log = false

  # Use default logging formatter so that PID and timestamp are not suppressed.
  config.log_formatter = ::Logger::Formatter.new

  # Do not dump schema after migrations.
  config.active_record.dump_schema_after_migration = false
end

注

• 我已经使用

  rake-assets:clean-RAILS\u-ENV=[environment]

  和

  rake-assets:clobber-RAILS\u-ENV=[environment]

• 我还尝试手动删除这些文件
• 我多次重新启动服务器
• 这是一个间歇性错误，似乎已经出现了几次，但它随机消失

所以我想我有两个问题

为什么我不能在本地复制？（这将是一个巨大的帮助）

为什么会在第一时间发生 地点

任何输入都值得赞赏。

仔细查看

公共/资产

后，css文件似乎正在生成，但URL与该文件不正确。似乎我需要将默认的css_压缩器更新为sass

config.assets.css_compressor = :sass

我本以为这已经是默认的了，但我想不是

仍然不确定为什么我不能在本地复制它
