Ruby Sinatra应用程序在Heroku上无误崩溃，但通过foreman-tips在本地运行良好？

我有一个简单的Sinatra应用程序，与Foreman一起在本地运行良好。但在Heroku上，它立即崩溃：

2013-09-17T18:52:37.449716+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=rfcstd.herokuapp.com fwd="38.122.223.90" dyno= connect= service= status=503 bytes=
2013-09-17T18:55:29.671059+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=rfcstd.herokuapp.com fwd="38.122.223.90" dyno= connect= service= status=503 bytes=

没有关于该错误的进一步信息

我的应用程序基于。我一直在尝试对Procfile和config.ru进行多次迭代，以使其正常工作，例如

Procfile.rb >
web: bundle exec ruby signing.rb -p $PORT

Answer:
Starting process with command `bundle exec rackup config.ru -p 14469`
configuration /app/config.ru not found

应用程序中没有包含config.ru，因此我尝试自己创建：

Procfile.rb >
web: bundle exec rackup ./config.ru -p $PORT
OR
web: bundle exec rackup config.ru -p $PORT

Config.ru >
require './signin.rb'
run Sinatra::Application

Answer:
at=error code=H10 desc="App crashed" method=GET path=/ host=rfcstd.herokuapp.com fwd="38.122.223.90" dyno= connect= service= status=503 bytes=

Google coded signin.rb启动了Sinatra，我认为这不是作为rack应用程序启动它的标准方式。Heroku似乎检测到了rack应用程序，但随后由于某些文件不可用而窒息。。。以下是signin.rb的一个片段：

##
# The Google+ Ruby Quickstart lets you get started with the Google+ platform
# in a few minutes.
#
# The app demonstrates:
#  * Using the Google+ Sign-In button to get an OAuth 2.0 refresh token.
#  * Exchanging the refresh token for an access token.
#  * Making Google+ API requests with the access token, including getting a
#    list of people that the user has circled.
#  * Disconnecting the app from the user's Google account and revoking tokens.

也许你没有安装所有的gems？@akonsu我在本地用bundle exec进行了测试，我在gems文件中有我需要的所有gems。此外，我认为Heroku会抱怨找不到宝石。奇怪的是没有错误通知。耶，我在评论中找到了答案：我在本地的另一个分支工作，它没有将其更改推送到Heroku。Heroku只推动主分支。哎哟正在工作：）
