我正在尝试让sinatra-asset-pipeline为我的 Sinatra 应用程序工作，这样我就可以让我的资产显示在 Heroku 上。我遵循 MVC 模式，目前正在将我的资产存储在project-folder/assets/stylesheets/application.scss. 我的config/environment.rb文件包含所有 gem 要求：

require 'bundler/setup'
Bundler.require
require 'sprockets'
require 'sinatra/activerecord/rake'
require 'sinatra/asset_pipeline/task'
require 'sinatra/asset_pipeline'
require 'sinatra/sprockets-helpers'
require 'rack-flash'
require 'sass/plugin/rack'
require_all 'app'

我在我的ApplicationController.

require './config/environment'

class ApplicationController < Sinatra::Base
  register Sinatra::Sprockets::Helpers
  register Sinatra::AssetPipeline
  set :sprockets, Sprockets::Environment.new('app')
  set :assets_prefix, '/assets'
  set :digest_assets, true

  configure do
    set :public_folder, 'public'
    set :views, 'app/views'
    sprockets.append_path File.join('app', 'assets', 'stylesheets')
  end

  get '/' do
    erb :'index'
  end

end

我的Rakefile包含运行 rake 任务的代码

Sinatra::AssetPipeline::Task.define! ApplicationController

当我跑步时，rake assets:precompile --trace我得到：

** Invoke assets:precompile (first_time)
** Execute assets:precompile

这会创建文件夹/public/assets/.sprockets-manifest-107e377ad857386671d3a9b56a890322.json。这个文件只包含这行代码：{}

我必须在我的控制器中指定asset_precompile 才能让我的rake 任务以正确的格式编译：set :assets_precompile, %w(application.css *.png *.jpg *.svg *.eot *.ttf *.woff *.woff2)我希望这个答案可以帮助其他任何在Sinatra 和资产管道中苦苦挣扎的人。

class ApplicationController < Sinatra::Base
  register Sinatra::Sprockets::Helpers

  set :assets_precompile, %w(application.css *.png *.jpg *.svg *.eot *.ttf *.woff *.woff2)

  register Sinatra::AssetPipeline
  set :sprockets, Sprockets::Environment.new('app')
  set :assets_prefix, '/assets'
  set :digest_assets, true

  configure do
    set :public_folder, 'public'
    set :views, 'app/views'
    sprockets.append_path File.join('assets', 'stylesheets')
  end

  get '/' do
    erb :'index'
  end

end
