Question

我正在通过Rails教程，我正在尝试将我的演示应用程序部署到Heroku，并且没有太多运气 - 当我访问该页面时，我收到“此页面不存在”错误。我可以在localhost服务器上运行该应用程序。我的日志在下面......我是Rails的新手，所以任何方向都会受到赞赏！

（如果重要的话，我正在运行Rails 4并使用Ruby 2.0.0p353。）

Answer 1

也许您没有指定根路径？您使用的是哪个教程？如果你正在做Hartl教程的第一部分，第一章应该显示你得到的错误（因为他们没有进入路由等可能会在下一章中发生） - http://ruby.railstutorial.org/ruby-on-rails-tutorial-book

Answer 2

将更改推送到Heroku后，我遇到了同样的问题。正如@derekyau指出的那样，这是因为heroku缺少根页。

添加指向欢迎页面的默认根页面，这解决了我的问题。要更新欢迎页面，请按照此处的说明进行操作：

Welcome/home page in Ruby on Rails - best practice

Heroku - “此页面不存在”错误
