heroku“您要查找的页面不存在。”遵循Hartl的RoR指南
[英]heroku “The page you were looking for doesn't exist.” following Hartl's RoR guide
问题描述
I'm following Michael Hartl's guide on learning Ruby on Rails and I just finished Chapter 5. 
我正在遵循迈克尔·哈特尔（Michael Hartl）关于学习Ruby on Rails的指南，我刚刚完成了第5章。
I get the localhost to load just fine and pages work and look as expected but when I try the final line to get heroku going "heroku open" I get the following screen ( http://take.ms/4KuwQ ). 我让localhost可以正常加载，并且页面可以正常工作，并且按预期方式运行，但是当我尝试最后一行使heroku进入“ heroku打开”状态时，我得到以下屏幕（ http://take.ms/4KuwQ ）。
I've tried checking other stackoverflow questions but still couldn't find the answer. 我试过检查其他stackoverflow问题，但仍然找不到答案。 The guide says to look at Heroku logs to debug but I can not find the solution. 该指南说要查看要调试的Heroku日志，但找不到解决方案。
Below is my entire Heroku log. 以下是我的整个Heroku日志。 I have also attached a screen grab ( http://take.ms/MaJhz ) of what I believe would be the issue but can not find the solution. 我还附上了我认为可能会导致问题但找不到解决方案的屏幕截图（ http://take.ms/MaJhz ）。

The screengrab log says no route matches a GET request on '/'. 屏幕截图日志显示没有路由与“ /”上的GET请求匹配。 Are you sure you've set a root route? 您确定设置了根路由吗？ It would look like this: (the routes file is found in 'config/routes.rb') 它看起来像这样：（在“ config / routes.rb”中找到了路由文件）
root to: 'controller#method'
Where controller is the controller you wish to use 'users' or 'posts' etc.. and the method would most likely be an index method. 其中controller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索引方法。
Take a quick look at routes.rb, and if you do have a line like I've mentioned above, just post up your routes.rb file for us to take a look. 快速浏览routes.rb，如果您确实有如上所述的一行，请发布您的routes.rb文件，让我们看看。
