这是我的代码：
require 'mms2r'
class IncomingMailHandler < ActionMailer::Base
##
# Receives email(s) from MMS-Email or regular email and
# uploads that content the user's photos.
# TODO: Use beanstalkd for background queueing and processing.
def receive(email)
begin
mms = MMS2R::Media.new(email)
##
# Ok to find user by email as long as activate upon registration.
# Remember to make UI option that users can opt out of registration
# and either not send emails or send them to a username+32523@example.com
# type address.
##
# Remember to get SpamAssasin
if (@user = User.find_by_email(email.from) && email.has_attachments?)
mms.media.each do |key, value|
if key.include?('image')
value.each do |file|
@user.photos.push Photo.create!(:uploaded_data => File.open(file), :title => email.subject.empty? ? "Untitled" : email.subject)
end
end
end
end
ensure
mms.purge
end
end
end
这是我的错误：

我向服务器发送了一封带有两个图像附件的电子邮件。收到电子邮件后，服务器运行“| ruby /xxx/script/runner 'IncomingMailHandler.receive STDIN.read'”
到底是怎么回事？我究竟做错了什么？
