我想获得一个rails 2.3.12项目运行在我的本地开发环境，但我似乎无法安装所需的宝石。这里是我正在使用的红宝石/钢轨版本：耙宝石：安装失败导轨2应用程序的神秘原因
$ rvm list
rvm rubies
...
=> ruby-1.8.7-p371 [ i686 ]
...
$ rails -v
Rails 2.3.12
这一切似乎都是为了。然而，当我尝试安装所需的宝石，我得到如下回应：
$ 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
由于到config/environment.rb是在跟踪所提到的，我会在这里将它包括在内：
# 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([email protected])
end
end
我不知道如何继续，而我研究这个问题的努力并没有带来任何帮助。任何援助将不胜感激。
编辑：
，我收到了类似的错误，如果我试图启动服务器：

问题不得不请使用ExceptionNotification插件（请参阅mt environment.rb文件的末尾），这很讽刺地引发了这种异常。该应用程序工作正常后，我重新安装插件。 – HandyAndyShortStack 2013-03-12 17:28:59
