無法獲得的Rails 3.1的服務器運行

Question

當我鍵入命令：軌服務器

我得到這個：

Usage: 
    rails new APP_PATH [options] 

Options: 
    -r, [--ruby=PATH]    # Path to the Ruby binary of your choice 
           # Default: /Users/chopps/.rvm/rubies/ruby-1.9.2-p290/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 
    -O, [--skip-active-record]  # Skip Active Record files 
    -S, [--skip-sprockets]   # Skip Sprockets files 
    -d, [--database=DATABASE]  # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db/sqlserver/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc) 
           # Default: sqlite3 
    -j, [--javascript=JAVASCRIPT] # Preconfigure for selected JavaScript library 
           # Default: jquery 
    -J, [--skip-javascript]  # Skip JavaScript files 
     [--dev]     # Setup the application with Gemfile pointing to your Rails checkout 
     [--edge]     # Setup the application with Gemfile pointing to Rails repository 
    -T, [--skip-test-unit]   # Skip Test::Unit files 
     [--old-style-hash]   # Force using old style hash (:foo => 'bar') on Ruby >= 1.9 

等......

任何想法，爲什麼服務器沒有啓動？

創建一個Rails應用程序後，請務必cd到應用程序的目錄中運行rails server之前。 rails server顯示，當你在一個項目的目錄目前是不是你提供的輸出。
