Using coffee-script with rails3.1 ubuntu 11.04

I have rails 3.1 insta开发者_运维知识库lled, and I try to use coffee script.

I get this:

node.js:63
   throw e;
         ^
Error: print() has moved. Use require('sys') to bring it back.
  at node.js:12:11

I use nodejs, 0.5.5 and npm 1.0.27

Have anybody seen this error? Thanks

Move to the stable branch of Node.js and all should be fine.
