I have been trying to install Fedena on Windows and following instructions from http://www.projectfedena.org/install

I am stuck on this step: Run the command "rake db:create". This will create the required databases. The database.yml file is as following:

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

I am getting the following error:

rake aborted! undefined method `[]' for nil:NilClass

(See full trace by running task with --trace)

仔细检查你的 database.yml 的格式；它只能缩进使用两个空格，而不是四个。

堆栈跟踪表明它找不到配置的“适配器”键；格式错误的 YAML 可能会导致这种情况。
