在heroku雪松堆栈上部署sinatra app（使用config.ru）

I'm trying to refactor my sinatra code to separate my main file into separate files, using some tips from this response, and I'm having troubles deploying to heroku.

我正在尝试重构我的sinatra代码,将我的主文件分成单独的文件,使用此响应中的一些提示,并且我遇到了部署到heroku的麻烦。

以前我没有config.ru文件,只使用了我的Procfile,它是:

web: bundle exec ruby web.rb -p $PORT

as per this article.

根据这篇文章。

From the refactor, I've now changed my Procfile to

从重构开始,我现在将我的Procfile更改为

web: bundle exec thin -R config.ru start -p $PORT

With my config.ru file being

我的config.ru文件正在

root = ::File.dirname(__FILE__)
require ::File.join( root, 'web' )
run MyApp.new

And my web.rb file being contained around a class definition

我的web.rb文件包含在类定义中

class MyApp < Sinatra::Application
  # ...
end

This works on my local development computer, but when I deploy to heroku, I get

这适用于我的本地开发计算机,但是当我部署到heroku时,我得到了

Is thin not installed on heroku? Or is there some other way of running my app on heroku with the changes?

瘦是没有安装在heroku上?或者是否有其他方法在heroku上运行我的应用程序?

I had to update my Procfile because the RACK_ENV isn't passed into the heroku environment. The Procfile became:

我不得不更新我的Procfile,因为RACK_ENV没有传递到heroku环境。 Procfile成为:
