我在ubuntu中运行rails的问题.当我键入rails它不启动服务器,而是给我这个消息:
kyala@ubuntu:~/depot$rails s Usage: rails new APP_PATH [options] Options: -r,[--ruby=PATH] # Path to the Ruby binary of your choice # Default: /home/kyala/.rvm/rubies/ruby-1.9.2-p290/bin/ruby -d,[--database=DATABASE] # Preconfigure for selected database (options: MysqL/oracle/postgresql/sqlite3/frontbase/ibm_db)enter code here # Default: sqlite3 -b,[--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) -m,[--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) [--dev] # Setup the application with Gemfile pointing to your Rails checkout [--edge] # Setup the application with Gemfile pointing to Rails repository [--skip-gemfile] # Don't create a Gemfile -O,[--skip-active-record] # Skip Active Record files -T,[--skip-test-unit] # Skip Test::Unit files -J,[--skip-prototype] # Skip Prototype files -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] # Supress status output -s,[--skip] # Skip files that already exist Rails options: -v,[--version] # Show Rails version number and quit -h,[--help] # Show this help message and quit Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify. 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.
