Ruby on rails 部署时，无法加载`Rails.application.database_configuration`无法加载数据库配置。没有这样的档案-

当我试图使用命令

gcloud app deploy

在谷歌云上部署ruby应用程序时，出现了以下错误，但当我运行以下命令时（在项目目录中）

bundle exec unicorn-c config/unicorn.rb

，它会工作，因此，

config/database.yaml

文件存在

我做错什么了吗？请告知。

可能需要特定环境的数据库配置。我假设您在

config/database.ym

中有开发配置。您可能需要为Gcloudit指定

production

configuration。它找不到设置变量的数据库文件。@muaaz，因此您的应用程序无法找到您的config/database.yml，您可以在本地运行此应用程序吗？如果可以，您可以发布您的database.yml和项目结构吗？我还建议你检查一下这些例子，我认为这会有所帮助。

runtime: ruby
env: flex
entrypoint: bundle exec unicorn -c config/unicorn.rb
