无法运行此Rails应用程序

Question

嘿，伙计们，我在Github中克隆了一个repo：https://github.com/huacnlee/homeland/tree/

当我运行服务器时，我得到了这个错误：

Agro:homeland Zhulin$ rails s
DEPRECATION WARNING: railtie_name is deprecated and has no effect. (called from <top (required)> at /Users/Zhulin/Desktop/RailsApps/homeland/config/application.rb:9)

    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

我该怎么办？顺便说一下，我在哪里可以找到学习Ruby和Rails的更简单的Rails代码，谢谢

Answer 1

您需要在config文件夹中设置一个config.yml文件。看起来存储库包含一个config.yml.default文件，您可以将其用作模板。

Answer 2

由于某种原因，您似乎丢失了数据库配置文件config/database.yml。这些都是由rails new <appname>自动生成的，因此很容易获得替换。

至于例子，一本好的参考书总是最好的。我喜欢Agile Web Development with Rails这本书，但还有很多其他的书。
