我是ruby和rails的新手,并且我在rails中安装了rails。但是当我通过键入“rails s”去启动服务器时,它不会启动并且出现以下消息。 但我可以通过命令栏new new_project创建一个新项目。请轨道专家帮助我。Rails服务器没有通过命令“Rails s”启动

# 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
