然后我在SO上提到几个答案并从终端运行以下命令： –

system@admin:~/apps/app_name/trunk$gem update --system 1.8.25

现在我收到错误： –

以下是我的environment.rb： –

# Be sure to restart your server when you modify this file

# Specifies gem version of Rails to use when vendor/rails is not present
RAILS_GEM_VERSION = '2.3.11' 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|

  config.gem 'jrails'

  # 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.autoload_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
end

以下是我的rakefile： –

# Add your own tasks in files placed in lib/tasks ending in .rake,# for example lib/tasks/capistrano.rake,and they will automatically be available to Rake.

require(File.join(File.dirname(__FILE__),'config','boot'))

require 'rake'
require 'rake/testtask'
require 'rdoc/task'
require 'tasks/rails'

以下是我提到的解决方案的答案： –

Uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)

undefined method `name’ for “actionmailer”:String

请帮我解决这个问题.
谢谢
