【问题描述】：
作为 Heroku 的新手，我在将基于 Sinatra 的简单应用程序部署到 Heroku 时遇到了很多麻烦。我已完成所有步骤，并且该应用程序也已部署。我已按照此处给出的说明进行操作：
https://blog.heroku.com/archives/2009/3/5/32_deploy_merb_sinatra_or_any_rack_app_to_heroku
我的 config.ru 文件如下：
require './sinatratest.rb'
run Sinatra::Application
我的 Gemfile 是
source 'https://rubygems.org'
gem 'sinatra'
Sinatratest.rb 如下：
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
并且 test.rb 包含以下 gem：
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 gem，但是当我这样做时，我的 Gemfile 看起来像这样，
source 'https://rubygems.org'
gem 'sinatra'
gem 'open-uri'
gem 'nokogiri'
gem 'json'
gem 'date'
当我运行bundle install 时，它给了我以下错误：
$ 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.
其余代码是程序的主要计算，所以我没有在这里包含它们。
当我在 localhost:4567 上运行文件时，程序运行完美。
在 Heroku 中运行应用程序时，我在日志文件中收到以下错误（相当广泛，不确定是否重要）：

我做错了什么？
【问题讨论】：
-
你不需要
gem 'date'这是在标准库中 -
@Sirl33tname 我会删除它，但这不会影响我的程序吗？因为它仍然在本地服务器上正常运行。
-
不是直接的，但是现在 heroku 可以安装你的 gem，你忘了添加 Procfile
-
@Sirl33tname blog.heroku.com/archives/2009/3/5/… 这并不要求我创建 Procfile。更重要的是，该应用程序顺利地被 Heroku 接受。跑步是个问题。
