    我正试图在本地开发环境中运行rails 2.3.12项目,但似乎无法安装所需的gem。以下是我正在使用的ruby/rails版本: 

    $ rvm list
rvm rubies
...
=> ruby-1.8.7-p371 [ i686 ]
...
$ rails -v
Rails 2.3.12

    这一切似乎都井然有序。然而,当我尝试安装所需的gem时,我得到了以下响应: 

    $ rake _0.9.2_ gems:install --trace
** Invoke gems:install (first_time)
** Invoke gems:base (first_time)
** Execute gems:base
** Invoke environment (first_time)
** Execute environment
rake aborted!

Tasks: TOP => environment

    由于跟踪中提到了config/enenvironment.rb,我也将在这里包括它: 

    # Be sure to restart your server when you modify this file
Encoding.default_external = Encoding::UTF_8 

# Specifies gem version of Rails to use when vendor/rails is not present
RAILS_GEM_VERSION = '2.3.12' unless defined? RAILS_GEM_VERSION

# Bootstrap the Rails environment, frameworks, and default configuration
require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|
  # Settings in config/environments/* take precedence over those specified here.
  # Application configuration should go into files in config/initializers
  # -- all .rb files in that directory are automatically loaded.

  # Add additional load paths for your own custom dirs
  # config.load_paths += %W( #{RAILS_ROOT}/extras )

  # Specify gems that this application depends on and have them installed with rake gems:install
  # config.gem "bj"
  # config.gem "hpricot", :version => '0.6', :source => "http://code.whytheluckystiff.net"
  # config.gem "sqlite3-ruby", :lib => "sqlite3"
  # config.gem "aws-s3", :lib => "aws/s3"

  # Only load the plugins named here, in the order given (default is alphabetical).
  # :all can be used as a placeholder for all plugins not explicitly named
  # config.plugins = [ :exception_notification, :ssl_requirement, :all ]

  # Skip frameworks you're not going to use. To use Rails without a database,
  # you must remove the Active Record framework.
  # config.frameworks -= [ :active_record, :active_resource, :action_mailer ]

  # Activate observers that should always be running
  # config.active_record.observers = :cacher, :garbage_collector, :forum_observer

  # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
  # Run "rake -D time" for a list of tasks for finding time zone names.
  config.time_zone = 'UTC'

  # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
  # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}')]
  # config.i18n.default_locale = :de

  config.after_initialize do
    ExceptionNotification::Notifier.exception_recipients = %w(applicationerror@seattlepub.com)
  end
end

    我不知道如何继续,我研究这个问题的努力也没有得到任何帮助。如有任何协助,我们将不胜感激。

    这个问题与ExceptionNotification插件有关(请参阅mt environment.rb文件的末尾),具有讽刺意味的是,它导致了这个异常。我重新安装插件后,该应用程序运行良好。
