首先让我说我对heroku/ruby/rails 很陌生。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，一切正常。但是，当我将我的应用程序推送到 heroku 并使用“heroku open”部署它时，应用程序似乎跳过了所有资产。我验证了资产管道已启用，但我仍然无法让我的应用程序以任何格式部署在 heroku 上。

我一直在查看 heroku 日志，但似乎唯一的错误是 FATAL SignalException 但我不确定那指的是什么。另外，如果有人可以解释弃用警告是否严重，我将非常感激。

heroku 日志：

不确定您遵循的过程，但heroku open不是部署您的应用程序，这只是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：

  1. 创建应用程序：heroku create
  2. 使用 git，将您的代码推送到 heroku：git push heroku master（heroku 是您的远程仓库的名称，用于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。
  3. 运行：（heroku run rake db:migrate你应该在 Gemfile 中使用 MySQL 或 Postgres，sqlite 会抛出错误）。
  4. 最后heroku open。

看起来你忘记了第 3 步。

希望这可以帮助！

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
