在Windows上安装Fedena时出错

Question

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)

Double-check the format of your database.yml; It should only be indented using two spaces, not four.

The stack-trace suggests that it can't find the 'adapter' key of your configuration; the mis-formatted YAML may be contributing to that.
