websocket - Meteor: Uncaught ReferenceError: SockJS is not defined -

i'm not sure of i've done mac os x 10.7.5, of sudden meteor v0.6.4 on node v0.8.25 started throw "uncaught referenceerror: sockjs not defined" in browser's console projects, fresh "hello world" created meteor create command. throwing error @ opening of page in browser, meteor doesn't allow happen further. error thrown in browser's console, while terminal keeps showing meteor server running on: http://localhost:3000/

i've tried remove , reinstall meteor, meteorite, node node_modules, rebooted several times, spent long hours searching solution in web, in vain.

this console tells me:

uncaught referenceerror: sockjs not defined stream_client_sockjs.js?6ef3fd3e8e39c1c357993f6936512726288ad127:164 _.extend._launchconnection stream_client_sockjs.js?6ef3fd3e8e39c1c357993f6936512726288ad127:164 meteor._ddpclientstream stream_client_sockjs.js?6ef3fd3e8e39c1c357993f6936512726288ad127:34 meteor._livedataconnection livedata_connection.js?5d09753571656c685bb10c7970eebfbf23d35ef8:36 _.extend.connect livedata_connection.js?5d09753571656c685bb10c7970eebfbf23d35ef8:1345 (anonymous function) client_convenience.js?4739936b2a334ad8041c3df27a37a5841b9d9842:16 (anonymous function) client_convenience.js?4739936b2a334ad8041c3df27a37a5841b9d9842:30

in stream_client_sockjs.js highlights following error:

self.socket = new sockjs( 

in livedata_connection.js highlights:

self._stream = new meteor._ddpclientstream(url); 

can please tell me how can restore functionality of meteor on computer? thank you!!
