导轨资产没有预编译，css在生产中看起来不同

Question

我的导轨应用程序在开发模式下工作，看起来完全按照我的要求，但在生产中它看起来不同铬和safari，在safari徽标图像加载但不是字体，在铬的字体加载，但没有图像加输入字段是一点点时间和铬对齐错误对齐，但在开发模式，这一切都看起来不错在铬

我一直在搞这一段时间，并删除公众/资产几次做

rake assets:precompile RAILS_ENV=production 

没有成功，预编译经过，没有任何错误

的config/application.rb中：

# Settings in config/environments/* take precedence over those specified here. 
# Application configuration should go into files in config/initializers 
# -- all .rb files in that directory are automatically loaded. 
config.assets.paths << "#{Rails.root}/assets/fonts" 
config.assets.paths << "#{Rails.root}/assets/images" 
config.assets.paths << Rails.root.join("app", "assets", "fonts") 
config.assets.precompile += %w(.svg .eot .woff .ttf) 


# Set Time.zone default to the specified zone and make Active Record auto-convert to this zone. 
# Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC. 
# config.time_zone = 'Central Time (US & Canada)' 

# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded. 
# config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s] 
# config.i18n.default_locale = :de 
config.assets.enabled = true 
#config.assets.paths << "#{Rails.root}/app/assets/fonts" 

配置/环境/制作：

# 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 thread 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 = true 
#config.assets.compile = true 

config.assets.precompile = ['*.js', '*.css', '*.css.erb', '*.css.scss'] 
# Compress JavaScripts and CSS. 
config.assets.js_compressor = :uglifier 
# config.assets.css_compressor = :sass 
config.assets.paths << "#{Rails.root}/assets/fonts" 
config.assets.paths << "#{Rails.root}/assets/images" 
config.assets.precompile += %w(.svg .eot .woff .ttf) 
config.assets.paths << Rails.root.join('app', 'assets', 'fonts') 
# Do not fallback to assets pipeline if a precompiled asset is missed. 
config.assets.compile = false 
config.assets.precompile << /(^[^_\/]|\/[^_])[^\/]*$/ 
# Generate digests for assets URLs. 
config.assets.digest = true 

# Version of your assets, change this if you want to expire all your assets. 
config.assets.version = '1.0'

在你config/environments/production.rb文件中，设置：

config.serve_static_assets = false（目前它设置为true）

config.assets.compile = true（目前设置为false）

这应该可以解决您的问题。

让我解释我要求你做的事情。

• 通过设置config.serve_static_assets = false，我们告诉轨服务器，不添加ActionDispatch::Static中间件，它是用来提供静态资产。

为什么不呢？

这是因为在生产环境中，您需要在Web服务器（如Apache/Nginx）后面运行应用服务器（如美洲狮），该服务器旨在直接提供静态文件（包括资产），而不会发送向rails应用服务器发送请求。

因为您没有使用任何网络服务器，我们正在关闭它。

• 通过设置config.assets.compile = true，我们告诉rails在运行时编译请求的资产。即在app/assets,vendor/assets,lib/assets中查找所请求的资产，如果从这些位置中的任何位置找到该资源，则会查找该资产。

默认情况下，config.assets.compile是true发展，false在生产环境中。因为我们没有使用Web服务器来提供静态资产，所以我们要求rails来编译我们的资产。
