我能做些什么来解决这个问题？我没有database.yml，这就是问题所在。然而，当我克隆回购协议时，它也没有。为什么它要寻找一个本来不应该存在的文件？

当人们在github上推送他们的repo时，他们会从该repo中排除配置文件。您需要创建一个database.yml文件以使应用程序正常工作

这里有一个例子

development:
  adapter: mysql
  database: bibapp_development
  username: root
  password: 

test:
  adapter: mysql
  database: bibapp_test
  username: root
  password:

production:
  adapter: mysql
  database: bibapp_production
  username: root
  password:

有没有办法让mysql自动创建这个文件？我只是不确定我应该在这里输入什么信息。比如，如果我只想创建一个空白数据库，以便测试正在运行的应用程序？你必须手动创建它。我猜您刚刚开始学习rails，所以很可能您正在开发模式中使用它。因此，请在其中输入mysql服务器的详细信息。默认情况下，您的用户名将是

root

没有密码。您只需输入数据库的名称，就可以了。是的，我对rails还是有点陌生。我不能在没有创建database.yml的情况下创建rake db:create，但是它在没有创建数据库的情况下请求数据库名称……有点混乱。当我在创建yml文件后尝试执行rake db:create时，我得到了以下错误：无法通过socket'/tmp/MySQL.sock'连接到本地MySQL服务器给定示例中的字段

database

用于指定数据库名称。创建一个数据库，然后在开发环境的

数据库

字段中指定其名称。
