在 heroku cedar 堆栈上部署 sinatra 应用程序(使用 config.ru) [英] Deploying sinatra app (with config.ru) on heroku cedar stack

问题描述

我正在尝试重构我的 sinatra 代码以将我的主文件分成单独的文件，使用来自此响应，我在部署到 heroku 时遇到了麻烦.

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.

以前我没有 config.ru 文件，只是使用了我的 Procfile，它是:

Previously I didn't have a config.ru file, and just used my Procfile, which was:

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

根据这篇文章.

从重构开始，我现在将 Procfile 更改为

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

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

我的 config.ru 文件是

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

我的 web.rb 文件包含在一个类定义中

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

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

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

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

2011-12-01T11:21:54+00:00 app[web.1]: bundler: command not found: thin
2011-12-01T11:21:54+00:00 app[web.1]: Install missing gem executables with `bundle install`
2011-12-01T11:21:56+00:00 heroku[web.1]: State changed from starting to crashed
2011-12-01T11:22:01+00:00 heroku[router]: Error H10 (App crashed) -> GET [my app].herokuapp.com/ dyno= queue= wait= service= status=503 bytes=

在heroku上没有安装thin吗?或者有没有其他方法可以通过更改在 heroku 上运行我的应用程序?

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

推荐答案

我不得不更新我的 Procfile 因为 RACK_ENV 没有传递到 heroku 环境中.Procfile 变成了:

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

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