Problem starting push server in Jugganaut

Hi All,

Im playing around with Jugganaut but stuck at the first step.

Seems the jugganaut push server requires json (which I have installed)
but it cant find it.

Following the docs, I have installed json and then try to run the push
server.

jonathan $ ruby script/push_server
script/push_server:37:in `require’: no such file to load – json
(LoadError)
from script/push_server:37

OK, so perhaps I didnt install json properly, so I try again.

jonathan $ sudo gem install json

lib/json/editor.rb:977:50: ‘:’ not followed by identified or operator

Seems to be installed this time. Try again to run the push server

jonathan $ ruby script/push_server
script/push_server:37:in `require’: no such file to load – json

from script/push_server:37

Anyone any ideas as to what could be wrong?

Thanks

Jonathan
