在Windows上安装Fedena时出错

Question

我一直试图在Windows上安装Fedena，并遵循http://www.projectfedena.org/install的说明

我被困在这一步:运行命令"rake :create“。这将创建所需的数据库。database.yml文件如下：

development:
      host: localhost
      adapter: mysql
      database: fedena_ultimate
      port: 3306
      username: root
      password: [redacted]
test: &test
      host: localhost
      adapter: mysql
      database: fedena_two_new
      port: 3306
      username: root
      password: [redacted]
production:
      host: localhost
      adapter: mysql
      database: fedena_ultimate
      port: 3306
      username: root
      password: [redacted]
cucumber:
  <<: *test

我得到了以下错误：

拉克流产了！零的未定义方法‘[]：NilClass (请参阅使用-- trace运行任务的完整跟踪)

重复检查您的database.yml的格式；它应该只使用两个空格，而不是四个空格。

堆栈跟踪表明它找不到配置的“适配器”键；格式错误的YAML可能是造成这种情况的原因。
