Rails资产没有预编译,css在生产中看起来不同

Question

在开发模式下我的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中看起来都很棒

我一直在弄乱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/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'

在您的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.

让我解释一下我要求你做的事情.

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

为什么不？

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),而无需将请求发送到rails应用服务器.

因为,您没有使用任何Web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,查找所请求的资产app/assets,vendor/assets,lib/assets和服务,如果从这些地点发现.

默认情况下,config.assets.compile正true处于开发阶段,false处于生产环境中.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.
