【问题描述】：

我在开发模式下遇到错误，我尝试了所有解决方案，但没有任何效果。我正在使用 rails v 5.1.4 和 ruby v 2.4.1

Started GET "/assets/images/logo.png" for ::1 at 2021-03-05 01:07:59 -0700

这是我的文件夹结构

这是查看文件 app/views/homepage/index.html.erb

<div style="background-image: url('/assets/images/logo.png')"></div>

这里是 assets.rb 文件 config/initializers/assets.rb

Rails.application.config.assets.version = '1.0'
Rails.application.config.assets.paths << Rails.root.join('node_modules')
Rails.application.config.assets.paths << Rails.root.join("app", "assets", "assets","images")

这里是 application.rb 文件 config/application.rb

require_relative 'boot'
require "rails"
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "action_cable/engine"
require "sprockets/railtie"
require "rails/test_unit/railtie"
Bundler.require(*Rails.groups)
module BorroupMobile
  class Application < Rails::Application
    config.load_defaults 5.1
    config.action_mailer.default_url_options = { :host => 'localhost' }
    config.session_store :cookie_store, key: '_interslice_session'
    config.middleware.use ActionDispatch::Cookies # Required for all session management
    config.middleware.use ActionDispatch::Session::CookieStore, config.session_options
    config.assets.enable=true
    config.api_only = true
    config.middleware.use ActionDispatch::Flash
    config.middleware.use(Rack::MethodOverride)
  end
end

在 production.rb 文件中，我添加了以下几行 config/environments/production.rb

config.assets.compile = true
config.assets.digest = false
config.serve_static_assets = false

在 production.rb 文件中，我添加了以下几行 config/environments/production.rb

config.assets.compile = true
config.assets.digest = false
config.serve_static_assets = false

我运行了 rake assets：预编译对我没有用

【解决方案1】：

你可以使用asset_path:

<div style="background-image: url('#{asset_path('logo.png')}')"></div>

<!-- asset_path('logo.png') will generate real path
=> /assets/logo-6d4bec8ad65e03a460fea1e6b84d71b.png -->

或者您可以在scss 文件中使用image-url：

/* assets/css/homepage.scss */
#homepage {
  background-image: image-url('logo.png');
}

【解决方案2】：

你可以试试这个：

background-image: image-url('logo.png') no-repeat;
