Question

我的开发模式下的rails应用程序工作和看起来完全符合我的要求，但在生产中它在chrome和safari上看起来不同，在safari中徽标图像加载但不是字体，在chrome中加载字体而不是图像加上输入字段有点长并且在chrome中不对齐但在开发模式下它们在chrome中看起来很棒

我一直搞乱了这个并且删除了公共/资产几次

rake assets:precompile RAILS_ENV=production

没有成功，预编译没有错误

配置/ 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/生产：

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

config.serve_static_assets = false （目前设置为true）

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

这可以解决您的问题。

让我解释一下我要求你做的事。

通过设置config.serve_static_assets = false，我们告诉rails服务器，不要添加用于提供静态资产的ActionDispatch::Static中间件。

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）后面运行您的应用程序服务器（如puma），该服务器旨在直接提供静态文件（包括资产），而无需发送请求rails应用程序服务器。

由于您没有使用任何网络服务器，我们将其关闭。

通过设置config.assets.compile = true，我们告诉rails在运行时编译所请求的资产。即，在app/assets，vendor/assets，lib/assets中查找所请求的资产，并在从这些位置找到时提供服务。

默认情况下，config.assets.compile在开发中为true，在生产环境中为false。由于我们没有使用Web服务器来提供静态资产，因此我们要求有效地编译我们的资产。

有关详细信息，请参阅asset pipeline documentation。

Rails资产没有预编译，css在生产中看起来不同
