我的应用在开发环境中运行时运行良好。在生产(rails server -e production)中,浏览器无法访问 css 和 js 文件,并且在控制台上会出现如下消息:

I, [2013-07-27T21:00:59.105459 #11449]  INFO -- : Started GET "/javascripts/application.js" for 99.102.22.124 at 2013-07-27 21:00:59 +0000
F, [2013-07-27T21:00:59.108302 #11449] FATAL -- : 
ActionController::RoutingError (No route matches [GET] "/javascripts/application.js"):

在生产环境中来自 html 源代码的 head 部分:

<head>
  <title>a Social Server</title>
  <link data-turbolinks-track="true" href="/stylesheets/application.css" media="all" rel="stylesheet">
  <link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css" rel="stylesheet">

另一方面,在开发环境中,头部部分看起来像:

该应用程序不使用数据库,因此我禁用了 ActiveRecord。配置文件的片段:

应用程序.rb

require File.expand_path('../boot', __FILE__)
#require 'rails/all'
require "action_controller/railtie"
require "action_mailer/railtie"
require "rails/test_unit/railtie"
require "sprockets/railtie"
Bundler.require(:default, Rails.env)
module Socialserver
  class Application < Rails::Application
  end
end

生产.rb

Socialserver::Application.configure do
   config.cache_classes = true
   config.eager_load = true
   config.consider_all_requests_local       = false
   config.action_controller.perform_caching = true
   config.serve_static_assets = false
   config.assets.js_compressor = :uglifier
   config.assets.compile = false
   config.assets.digest = true
   config.assets.version = '1.0'
   config.log_level = :info
   config.i18n.fallbacks = true
   config.active_support.deprecation = :notify
   config.log_formatter = ::Logger::Formatter.new
   config.assets.paths << Rails.root.join('app', 'assets', 'fonts')
   config.assets.precompile += %w( .svg .eot .woff .ttf )
end

开发.rb:

Socialserver::Application.configure do
  config.cache_classes = false
  config.eager_load = false
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false
  config.action_mailer.raise_delivery_errors = false
  config.active_support.deprecation = :log
  config.assets.debug = true
end

宝石文件:

gem 'rails', '4.0.0'
gem 'sass-rails', '~> 4.0.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'

我为发布这么多信息而道歉。我觉得这些信息可能是相关的。

ps 我对rails 的知识只有半生不熟,所以请多多包涵。谢谢~

在本地测试您的生产环境时,您必须在本地编译资产。只需运行以下命令:

RAILS_ENV=production bundle exec rake assets:precompile

它将生成public/assets.

接下来,您必须告诉 Rails 自己服务资产。服务器软件(例如 Nginx 或 Apache)在 Heroku 等环境中为您执行此操作,但在本地您应该让 Rails 执行此操作。在你的改变这个production.rb

config.serve_static_assets = true

但请确保false在将代码推送到生产环境之前将其设置回!

这听起来像是我遇到的问题

我发现一个博客表明这是 Rails 4.0.0 资产管道中的一个错误,并且通过设置...

config.assets.compile = true

... 在config/environments/production.rb

除了以某种方式将资产管道投入实际工作之外,该设置还将开启资产的实时编译。这对于生产中的性能通常是一件坏事,但是如果您在部署时仍然手动预编译资产,使用

rake assets:precompile

...实时编译不应该发生(因为必要的资产已经预编译)。

我希望这有帮助 :)

如前所述config.serve_static_assets,已弃用并由config.serve_static_files. 如果检查config/environments/production.rbRails-4.2,就会发现:

  # Disable serving static files from the `/public` folder by default since
  # Apache or NGINX already handles this.
  config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?

这意味着在export RAILS_SERVE_STATIC_FILES="to any value whatsoever"运行之前在会话中设置和导出(在 BASH 中)环境变量rails s -e production将在本地测试时给出所需的结果,并且还将避免production.rb在推送到生产主机之前必须记住重新编码。

在 production.rb 中更改设置:

导轨 3.x

config.serve_static_assets = true

导轨 4.x

config.serve_static_files = true

检查这样的文件:

public/assets/.sprockets-manifest-3f7771d777ceb581d754e4fad88aa69c.json

如果您将预编译的资产推送到生产服务器,那么您可能会阻止隐藏的“点”文件被推送,而这个基本文件将无法投入生产。

在我的环境中,我需要在集成环境中预编译资产并将其推送到生产环境中,这样就无需在生产机器上编译资产。我错误地阻止了所有隐藏文件被推送到生产机器。

要查看此答案是否适合您,请在生产服务器的浏览器中检查您生成的 HTML 源代码,以查看是否已生成资产路径。如果你看到你的脚本标签是这样的:

<script data-turbolinks-track="true" src="/javascripts/application.js"></script>

检查 src 属性。它应该以/assets/javascript. 在这种情况下,它以/javascriptwhich 开头,表示 Rails 认为任何资产都没有被预编译。

我通过将推送更新到生产(当前为 rsync)来纠正此问题,确保.sprockets-manifest*在我的集成服务器上预编译后推送文件。

此外,我使用独立的 Passenger 作为我的集成测试服务器,而不是 Webrick,因为它可以处理更真实的静态文件服务。

在 Rails 5.x 中,设置为

配置/初始化程序/assets.rb:

Rails.application.config.public_file_server.enabled = true

我认为对于 Rails 4.x,您必须将资产预编译到生产环境中,或者在需要时使用 config.assets.compile 。

生产环境的默认 Rails 行为是“如果错过了预编译的资产,不要回退到资产管道”。所以,不要。用于不编译

config.assets.compile = false

如果您使用此选项,则无需使用:

config.serve_static_files = true

因为如果资产没有预编译,Rails 将在服务请求之前编译。

但是,如果您在生产之前预编译资产,则不需要config.assets.compile = true,但config.serve_static_files = true如果您没有 http_server 来提供预编译资产,则需要 Rails 服务请求。

该设置config.serve_static_assets已弃用。

DEPRECATION WARNING: The configuration option `config.serve_static_assets` has been renamed to `config.serve_static_files` to clarify its role (it merely enables serving everything in the `public` folder and is unrelated to the asset pipeline). The `serve_static_assets` alias will be removed in Rails 5.0. Please migrate your configuration files accordingly.

我希望这个答案可以帮助您(读者)了解真正发生的事情

以下命令在本地适用于我。

rails server -e production

我在运行“rails s”时遇到了同样的错误“ActionController::RoutingError (No route matches [GET] "/assets/application.css""。即使在我预编译了源代码后,将配置预编译更改为 true。它仍然无法加载适当地。

选项“-e production”使那些 RoutingError 消失了。
