Ruby 在Heroku上部署Sinatra应用程序时出错

作为Heroku的新手，我在将简单的基于Sinatra的应用程序部署到Heroku时遇到了很多麻烦。我已经完成了所有步骤，应用程序也得到了部署。我已经按照这里给出的说明进行了操作：

我的config.ru is文件如下所示：

require './sinatratest.rb'
run Sinatra::Application

我的档案是

source 'https://rubygems.org'
gem 'sinatra'

Sinatratest.rb如下所示：

require 'sinatra'
require './test.rb'

get '/'  do
    result = FooRunner.run!

     File.open('output.json','w') do |f|
        f.write result
     end

    content_type :text
    result
end

和test.rb包括以下gems：

require 'rubygems'
require 'nokogiri'
require 'open-uri'
require 'date'
require 'json'

我的直觉告诉我应该在Gemfile中包含所有的宝石，但是当我这样做时，我的Gemfile看起来是这样的

source 'https://rubygems.org'
gem 'sinatra'
gem 'open-uri'
gem 'nokogiri'
gem 'json'
gem 'date'

当我运行

bundle install

时，会出现以下错误：

$ bundle install
Fetching gem metadata from https://rubygems.org/.........
Fetching gem metadata from https://rubygems.org/..
Resolving dependencies...
Could not find gem 'date (>= 0) x86-mingw32' in the gems available on this
machine.

其余的代码是程序的主要计算，所以我没有在这里包括它们

当我在localhost:4567上运行这些文件时，程序运行得非常好

在Heroku中运行应用程序时，我在日志文件中发现以下错误（相当广泛，不确定是否重要）：
