我曾尝试使用Google的解决方案，但我不能找到任何东西。

你有运行移民？你的日志说你没有database.yml文件 – Debadatt

，它不会通过运行迁移来修复，你必须决定使用哪个数据库，然后用这个配置创建一个database.yml文件。 –

不，我没有。我是否像这样创建它？ http://stackoverflow.com/questions/6824036/rails-local-server-error-no-such-file-database-yml – Fawky

您的第一行错误表示您没有config/database.yml文件。

你的应用程序中创建一个database.yml文件config目录和

在database.yml文件

development: 
    adapter: sqlite3 
    database: db/development.sqlite3 
    pool: 5 
    timeout: 5000 


test: 
    adapter: sqlite3 
    database: db/development.sqlite3 
    pool: 5 
    timeout: 5000 


production: 
    adapter: sqlite3 
    database: db/development.sqlite3 
    pool: 5 
    timeout: 5000

谢谢你，之后我做了rake db：migrate，现在它工作的很完美。 – Fawky

第一行显示您的问题：

/Users/falk/.rvm/gems/ruby-1.9.3-p448/gems/railties-3.2.12/lib/rails/application/configuration.rb:115:in `read': No such file or directory - /Users/falk/Desktop/parkbuddy/config/database.yml (Errno::ENOENT)

的config/database.yml文件不存在在你的Rails应用程序。查看应用程序的文档以了解它对数据库配置的建议。
