Install api-console-cli failed

Running api-console build helloworld.raml failed， Whether it's local files or web resources.

#helloworld.raml
#%RAML 1.0
title: Hello world # required title

/greeting: # optional resource
  get: # HTTP method declaration
    responses: # declare a response
      200: # HTTP status code
        body: # declare content of response
          application/json: # media type
            # structural definition of a response (schema or type)
            type: object
            properties:
              message: string
            example: # example how a response looks like
              message: "Hello world"

I got the error message:

  Building the API console. This may take a moment.

Warning: You are trying to use local RAML file as an input but the --use-json optionis not set.
