【问题描述】：

我不知道为什么我不能使用rake -T 或bundle exec rake -T

# app.rb

require 'rubygems'
require 'sinatra'
require "sinatra/activerecord"

class App < Sinatra::Base
  #configuraciones
  set :root, File.dirname(__FILE__)
  set :session_secret, 'super secret'
  set :public_folder, File.dirname(__FILE__) + '/public'
  set :layout, 'views/layouts'
  set :database, {adapter: "sqlite3", database: "data"}
  enable :sessions
  #before all requests
  before do
    headers['server'] = 'Ruby, Ubuntu'
  end
  #registro de helpers de la aplicacion
  helpers Sinatra::App::Helpers::Applicaction
  helpers Sinatra::App::Helpers::Filters
  #registro de helpers de routes
  helpers Sinatra::App::Helpers::ErrorHelper
  #registro de rutas
  register Sinatra::App::Routing::Home
  register Sinatra::App::Routing::Departamento
  register Sinatra::App::Routing::Provincia
  register Sinatra::App::Routing::Error
end

# Rakefile.rb

require 'sinatra'
require "sinatra/activerecord/rake"
require './app'

# config.ru

require_relative 'config/boot'
require File.dirname(__FILE__) + '/app'

run App

这是错误信息：

PS C:\ruby\sinatra> bundle exec rake -T
WARNING: If you plan to load any of ActiveSupport's core extensions to Hash, be
sure to do so *before* loading Sinatra::Application or Sinatra::Base. If not,
you may disregard this warning.

PS C:\ruby\sinatra>

这是文件结构：

更新 首先更改 app.rb

helpers Sinatra::App::Helpers::Application

这是 helpers.rb

 module Sinatra
  module App
    module Helpers
      module Application
        def load_css(csss)
          rpta = ''
          if defined? csss
            csss.each do |css|
              temp = '<link href="' + CONSTANTS[:static_url] + css + '.css" rel="stylesheet"/>'
              rpta = rpta + temp
            end
          end
          rpta
        end

        def load_js(jss)
          rpta = ''
          if defined? jss
            jss.each do |js|
              temp = '<script src="' + CONSTANTS[:static_url] + js + '.js" type="text/javascript"></script>'
              rpta = rpta + temp
            end
          end
          rpta
        end
      end
    end
  end
end

我有同样的错误

【问题讨论】：

错误似乎是指helpers Sinatra::App::Helpers::Applicaction这一行——Sinatra::App::Helpers::Applicaction在哪里定义？那是正确的命名空间吗？你能显示它的来源吗？
如果你把require "sinatra/activerecord/rake" 放在rakefile 的第一行会发生什么？
Applicaction 是错字吗？
@Stefan 我会告诉你我把代码忘在家里了
@lacostenycoder 我想我做到了，但我会再试一次

【解决方案1】：

我解决了我必须在 app.rb 中添加的问题

require File.dirname(__FILE__) + '/config/initializers/helpers.rb'
require File.dirname(__FILE__) + '/config/initializers/filters.rb'
require File.dirname(__FILE__) + '/helpers/error_helper.rb'
require File.dirname(__FILE__) + '/routes/error.rb'
require File.dirname(__FILE__) + '/routes/home.rb'

但我不知道为什么我的 boot.rb 不起作用

config.ru

#!/usr/bin/env rackup
# encoding: utf-8

require_relative 'config/boot'
require File.dirname(__FILE__) + '/app'

run App

boot.rb

#registro de rutas
Dir["./routes/*.rb"].each {|file| require file }
#registro de initializers
Dir["./config/initializers/*.rb"].each {|file| require file }
#registro de modelos
Dir["./models/*_model.rb"].each {|file| require file }
#helpers
Dir["./helpers/*_helper.rb"].each {|file| require file }
