Sinatra 引导错误，无法加载此类文件

Question

我正在创建一个 Ruby 应用程序，当我尝试运行它时，我收到一条错误消息，提示它无法加载文件。

在我的主文件 app.rb 中，我试图要求 models/issue

require "models/issue"

class App < Sinatra::Base
  enable :sessions
  register Sinatra::Flash

  get "/" do
    "redirect/issues" 
  end   

  get "/issues" do 
    @issues = Issue.all 

    haml :"issues/index"
  end   
end

当我使用 shotgun 时，出现以下错误：

Boot Error

Something went wrong while loading config.ru

LoadError: cannot load such file -- models/issue

我认为文件路径没有问题。我的路径如下所示：

ProjectName
  config.ru
  lib
    app.rb
    models
      issue.rb

这是我的 config.ru 文件：

require "./env"
require "./lib/app"

run App

这是我的 models/issue 文件：

class Issue 
  include Mongoid::Document
  include Mongoid::Timestamps::Updated

  field :name, type: String
  field :description, type: String
end

有

 require_relative 'models/issue'

或

 require './models/issue'
