runkit sandbox not working

[pashute]

The main node-julia Readme.md sends us to a Runkit + npm sandbox where we can try it out live

But the site doesn't work.

I write

julia = require('node-julia');
var a = julia.eval('[ 1 2 3 ; 3 4 1; 8 2 9]');
var b = julia.eval("[1 1 1]'");
var c = julia.exec('\\',a,b);

and get:

Error: Could not locate the bindings file. Tried:
