我使用命令rails new publication
创建了一个新的应用程序我已经使用rails s命令在本地计算机（Windows 7计算机）上运行它。它工作正常，并显示rails默认页面。
当我通过命令git push heroku master将它推送到heroku服务器时，它已成功上传但不起作用。它显示错误
https://quiet-spire-3568.herokuapp.com/
这是我的heroku日志

默认的“欢迎”页面仅在开发中提供，因此在生产中获得404是正常的。
该页面由作为rails gem的一部分的控制器和模板提供，您可以看到here仅在开发中添加到它的路由。

请在路线中设置以下内容：
root to: 'pages#main'
其中page是控制器名称，main是方法

您需要在生产中手动配置主页，因为默认主页仅适用于开发模式。
要解释文档，请执行以下操作：
rails generate controller Greetings
然后转到app/controllers/greetings_controller.rb并略微修改：
class GreetingsController < ApplicationController
def index
@message = "Hello, how are you today?"
end
end
然后转到app/views/greetings/index.html.erb并执行此操作：
<h1>A Greeting for You!</h1>
<p><%= @message %></p>
最后在config/routes.rb：
root :to => 'greetings#index'
顺便说一下，这也会让你点击/greetings。

在你的config / application.rb中，尝试将其添加到最后一行（在“结束”之前...
config.assets.initialize_on_precompile = false
如果你用Git推送Heroku，你会想要用这一行重新提交。否则，请使用此行启动新的Heroku应用程序。关于您在尝试解决这个问题时所做的任何其他更改的Idk，但是当我以前使用Heroku时，这条线必需才能使用它。祝你好运！
