rails:无法加载数据库配置.没有这样的文件 -

Question

我从GitHub存储库中克隆了一个app文件夹,在bundle安装了gem之后,我尝试使用rake db:setup和rake db:migrate命令,两者都没有工作,这是我的错误信息:

**arun997@promanager:~/workspace (master) $ rake db:setup
require 'rails/all'... 2.470s
Bundler.require... 7.590s
rake aborted!
Cannot load `Rails.application.database_configuration`:
Could not load database configuration. No such file - 
/usr/local/rvm/gems/ruby-2.2.1/gems/railties-4.1.13/lib/rails/application/configuration.rb:105:in `database_configuration'

如果有人可以提供帮助,我将永远感激不尽.

Answer 1

您的rails应用程序会丢失该文件:

/your-app-path/config/database.yml

如果是这样,你可以用这些例子创建一个新的

Answer 2

从 .yml 文件中删除 .example 扩展名

     database.yml.example -> database.yml
