Question

我一直在尝试将一个简单的rails应用程序部署到heroku上，但我完全没有成功。

我正在使用Viking Code School准备工作在Mac终端上完成“Railsfest安装”。这是我一直关注的确切链接：

http://docs.railsbridge.org/installfest/deploy_a_rails_app

我的问题是看起来我已经成功部署了应用程序，但是如果你去了链接：

https://powerful-river-94011.herokuapp.com

根据heroku的标准输出，你可以清楚地看到“出了问题”......

我一直在努力解决这些命令之间的问题：

gem install bundler
bundle install --without production

我已经在routes.rb文件中正确设置了文件，并且我还将所有更改都提交给了git：

git add .
git commit -m "Updates for heroic deployment"

我已经成功地完成了以下任务：

git push heroku master

在推送成功之前我通过将一个Procfile添加到测试应用程序的根路径，更改gem文件以包含正在使用的ruby版本，使用我想要的显式版本更新bundler，更新Xcode，以及其他任何你可以在网上找到的关于此事的内容。

我达到了我所知道的解决这个问题的程度，剩下的就是阅读日志，但我不知道该怎么做。

下面的

是这个问题的日志文件，如果你能帮助我查明引起我头痛的区域，我将非常感激。

可能甚至设置了赏金!!!
