在Heroku上部署Sinatra應用程序給出錯誤

作爲Heroku新手，我在Heroku中部署簡單的基於Sinatra的應用程序時遇到了很多麻煩。我已經遵循了所有步驟，並且應用程序也已部署。我已經按照這裏給出的說明：在Heroku上部署Sinatra應用程序給出錯誤

https://blog.heroku.com/archives/2009/3/5/32_deploy_merb_sinatra_or_any_rack_app_to_heroku

我config.ru是文件如下：

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

我的Gemfile是

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

Sinatratest.rb是如下：

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

而且test.rb包括以下寶石：

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

我的直覺告訴我，我應該被包括在Gemfile中所有的寶石，但是當我做我的Gemfile看起來像這樣，

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

當我運行bundle install，它給了我下面的錯誤：

$ 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.

的代碼的其餘部分是該方案的主要計算，所以我還沒有includ在這裏編輯他們。

當我在localhost：4567上運行文件時，程序運行完美。

在在Heroku上運行的應用程序，我得到（如果它是相當廣泛的，不知道是重要的）在日誌文件中的以下錯誤：

我究竟做錯了什麼？

你不需要'gem'date''這是在標準庫中 –

@ Sirl33tname我會刪除那個，但那不影響我的程序嗎？因爲它仍然可以在本地服務器上正常運行。 – Newtt

不是直接，但現在heroku可以安裝你的寶石，你忘了添加一個Procfile –

你崩潰提到

cannot load such file -- nokogiri

你Gemfile應該列出你所有的需要的寶石，否則的Heroku無法加載它們。嘗試將Nokogiri添加到您的Gemfile中。如上所述，您不需要添加日期，open-uri或JSON，因爲這些是標準庫。
