我是ruby和rails的新手,並且我在rails中安裝了rails。但是當我通過鍵入「rails s」去啓動服務器時,它不會啓動並且出現以下消息。 但我可以通過命令欄new new_project創建一個新項目。請軌道專家幫助我。Rails服務器沒有通過命令「Rails s」啓動

# 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
