我使用的是rails 2.3.11，ruby-1.9.2-p320。 尝试运行脚本/服务器，但收到此错误： -

然后我在SO上提到了一些答案并从终端运行了以下命令： -
system@admin:~/apps/app_name/trunk$ gem update --system 1.8.25
现在收到错误： -

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

Ruby 1.9.2并不是那么新，你应该使用1.9.3-p448。 Rubygems 1.8.25非常老，应该只与Ruby 1.8一起使用AFAIK。你可能正在使用一个非常古老的发行版。尝试使用rvm安装最新的Ruby 1.9和Rubygems。这是一个简短的快速入门指南。如果遇到麻烦，请参阅文档。
\curl -L https://get.rvm.io | bash -s stable
rvm install 1.9
rvm use 1.9 --default
rvm rubygems latest --verify-downloads 1
gem install bundler
bundle exec ./script/server

将mysql.yml文件中的mysgl适配器更新为mysql2
development:
adapter: mysql2
database: app_db
username: root
password: root
host: localhost
安装mysql2适配器
gem install activerecord-mysql2-adapter
然后，从config / environment.rb安装缺少的gem：
rake gems:install
将项目文件夹内的服务器文件的执行权限赋予：
chmod u+x ./script/server
启动服务器：
chmod u + x ./script/server
./script/server start或./script/server或exec script/server
