juggernaut error

i am trying to experiment with Jugger开发者_C百科naut plugin using chat_sandbox example.

i get this error message

Juggernaut: There has been an error connecting on 127.0.0.1:5001

I have no idea what it means.

my juggernaut.yml is as follows

:hosts:
  - :port: 5001
    :host: 127.0.0.1
    :public_host: 127.0.0.1
    :public_port: 5001
    # :secret_key: your_secret_key
    # :environment: :development

Thanks in advance.

Have you started juggernaut?

juggernaut -c juggernaut.yml

Then juggernaut will write something like Starting Juggernaut server 0.5.8 on port: 5001... or will return an error.
