Question

首先让我说我是heroku / ruby / rails的新手。我正在阅读Michael Hartl的Ruby on Rails教程，当我使用'rails s'在本地服务器上部署我的应用程序时，一切都显示正常。但是，当我将我的应用程序推送到heroku并使用“heroku open”进行部署时，应用程序似乎跳过所有资产。我确认资产管道已启用，但我仍无法使用任何格式将我的应用程序部署到heroku上。

我一直在查看heroku日志，但似乎唯一的错误是FATAL SignalException，但我不确定这是指什么。此外，如果有人能够解释折旧警告是否严重，我会非常感激。

heroku日志：

Answer 1

不确定您遵循的流程，但heroku open不会部署您的应用程序，只能在您的浏览器中打开yourapp.herokuapp.com。

要在heroku中部署应用程序，您必须：

创建应用：heroku create
使用git，将代码推送到heroku：git push heroku master（heroku是远程仓库的名称，使用git remote -v确保您拥有heroku）。这会将您的应用程序部署到heroku，捆绑安装，创建数据库并预编译您的资产。
运行：heroku run rake db:migrate（您应该在Gemfile中使用MySQL或Postgres，sqlite会抛出错误）。
最后heroku open。

看起来你忘记了第3步。

希望这有帮助！

Answer 2

您是否可能错过了5.4中的步骤？

require File.expand_path('../boot', __FILE__)
.
.
.
 module SampleApp
  class Application < Rails::Application

    config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif)
 end
end

Heroku部署没有格式化？
