Question

我正在关注Michael Hartl关于学习Ruby on Rails的指南，我刚刚完成了第5章。

我让localhost加载得很好并且页面工作并且看起来像预期的那样但是当我尝试最后一行让heroku继续“heroku open”时，我得到以下屏幕（http://take.ms/4KuwQ）。

我已经尝试检查其他stackoverflow问题，但仍然找不到答案。该指南说要查看Heroku日志进行调试，但我找不到解决方案。

以下是我的整个Heroku日志。我还附上了一个屏幕抓取（http://take.ms/MaJhz）我认为会出现问题，但无法找到解决方案。

整个GEM文件：

source 'https://rubygems.org'
ruby '2.0.0'

screengrab日志表示没有路由匹配'/'上的GET请求。你确定你已经设置了根路线吗？它看起来像这样:(路径文件在'config / routes.rb'中找到）

root to: 'controller#method'

如果控制器是您希望使用“用户”或“帖子”等的控制器。并且该方法很可能是一种索引方法。

快速浏览一下routes.rb，如果你有像我上面提到的那样的行，只需发布你的routes.rb文件给我们看看。
