我试图在我的项目中使用newrelic。我已经成功安装了newrelic gem，下一步是添加config.gem＆＃34; newrelic_rpm＆＃34;到environment.rb
当我在environment.rb中使用config.gem时，我无法启动 Ruby on Rails应用程序但是使用 config.gem＆＃34; dfgdsgsdgsdfg＆＃34; 会导致同样的错误。
我该如何解决这个问题？
我正在运行Debian Linux，Apache2，RVM 1.8.6，Passenger 3，Rails 2.3.5，Ruby 1.8.7，gem 1.8.10
这是我的environment.rb
RAILS_GEM_VERSION = '2.3.5' unless defined? RAILS_GEM_VERSION
require File.join(File.dirname(__FILE__), 'boot')
Rails::Initializer.run do |config|
config.gem "newrelic_rpm"
config.time_zone = 'UTC'
config.action_mailer.delivery_method = :smtp
config.action_mailer.default_content_type = "text/html"
config.action_mailer.smtp_settings = {
:address => "smtp.xxx.xx",
:port => 25,
:domain => "xxxx.com",
:authentication => :login,
:user_name => "site@xxxxx.com",
:password => "xxxxx"
:enable_starttls_auto => true
}
end
和完全回溯
Ruby on Rails application could not be started
Error message:
undefined method `name' for "actionmailer":String
Exception class:

前言：我为New Relic工作。
而不是使用config.gem只需添加：
require "newrelic_rpm"
在初始化程序之后它应该工作得很好:)我希望我有理由为什么你必须这样做，但我不这样做。当我还在使用Rails 2.x应用程序时，我记得这只是一个“技巧”（我从来没有好运过config.gem）。
