ClosureScript & NodeJS: Error: No *print-fn* fn set for evaluation environment

Question

I have followed the "hello world!" examples for NodeJS on both these guides

• https://github.com/clojure/clojurescript/wiki/Quick-Start#running-clojurescript-on-nodejs
• http://mmcgrana.github.io/2011/09/clojurescript-nodejs.html

and for each I get this error

Error: No *print-fn* fn set for evaluation environment

Have I missed a step? This seems like a fairly basic problem ... does anyone know where print-fn is set?

Answer 1

You can say

(enable-console-print!)

to print using console.log.

Under the hood, enable-console-print! sets *print-newline* and *print-fn*. Here's the source as of r2156.
