$ rails server

Usage: rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]              # Path to the Ruby binary of your choice
                                 # Default: /home/bikram/.rvm/rubies/ruby-1.9.3-p448/bin/ruby

  -b, [--builder=BUILDER]        # Path to a application builder (can be a filesystem path or URL)
  -m, [--template=TEMPLATE]      # Path to an application template (can be a filesystem path or URL)
      [--skip-gemfile]           # Don't create a Gemfile
      [--skip-bundle]            # Don't run bundle install
  -G, [--skip-git]               # Skip Git ignores and keeps

Runtime options:
  -f, [--force]    # Overwrite files that already exist
  -p, [--pretend]  # Run but do not make any changes
  -q, [--quiet]    # Suppress status output
  -s, [--skip]     # Skip files that already exist

Rails options:
  -h, [--help]     # Show this help message and quit
  -v, [--version]  # Show Rails version number and quit

Description:
    The 'rails new' command creates a new Rails application with a default
    directory structure and configuration at the path you specify.

    You can specify extra command-line arguments to be used every time
    'rails new' runs in the .railsrc configuration file in your home directory.

    Note that the arguments specified in the .railsrc file don't affect the
    defaults values shown above in this help message.

Example:
    rails new ~/Code/Ruby/weblog



    This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
    See the README in the newly created application to get going.

它是这样生成的，但不是 rails 本地服务器。其他版本有:

rails 3.2.14

ruby 1.9.3p448 (2013-06-27 修订版 41675) [i686-linux]

gem 2.1.9

rvm 1.23.9(稳定)

我的 gem 文件是:

source 'https://rubygems.org'

gem 'rails', '3.2.14'

group :development, :test do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.11.0'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.5'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.2'

group :test do
  gem 'capybara', '1.1.2'
end

group :production do
  gem 'pg', '0.12.2'
end

这是当您尝试在没有 Rails 应用程序的文件夹中启动 Rails 服务器时生成的默认消息。

您需要运行 rails new <appname>其中 appname 是您在启动服务器之前所在的文件夹。

如果它是一个 Rails 应用程序，那么您可能会遗漏服务器命令用来确定它是否是一个 Rails 应用程序的一些关键文件。
