我又仔细的看了一遍，并且我自己跑了一下，我的是可以用的
你的问题看着像是Rmaick的问题，要是不行的话，建议你重新下载

[url=http://rubyforge.org/frs/download.php/46136/RMagick-2.7.1-ImageMagick-6.4.5-3-Q8.zip]RMagick-2.7.1-ImageMagick-6.4.5-3-Q8.zip[/url]

安装，我是用的这个，因为，我看你是windows下的

解压缩，装一个exe，gem install一个gem，保证都不出错再运行

[code="linux"]rake db:create [/code]

[code="linux"]rake db:migrate[/code]

* Ruby 1.8.6 +
* Rails 2.0 +
* RMagick
* MySQL 数据库

这是人家的要求，而且
我的smtp总是不对所以，我把email.rb改了
#ActionMailer::Base.delivery_method = CHITO_CONFIG[:mail][:method]
#ActionMailer::Base.smtp_settings = CHITO_CONFIG[:mail][:settings]

[code="ruby"] # config/environments/development.rb
ActionMailer::Base.raise_delivery_errors = true

set delivery method to :smtp, :sendmail or :test

#config.action_mailer.
ActionMailer::Base.delivery_method = :smtp

these options are only needed if you choose smtp delivery

#config.action_mailer.
ActionMailer::Base.smtp_settings = {
:address => 'smtp.gmail.com',
:port => 587,
:authentication => :plain,
:user_name => '[e-mail]', #你的gmail帐号
:password => 'password' #你的gmail密码
}[/code]

参考吧，希望有帮助
