Cannot run tests

[GeoffreyBooth]

I‘m trying to get this to run. Under Node 7.1.0, after npm install when I run npm test I get:

classes interop
classes interop ✘

FAILURE: 0/0 tests ran successfully; 0 failed, 0 incomplete, 1 errors

Error #1:
classes interop
Error: Deprecated configuration property [onError] given to TaskGroup::setConfig()

If I lock the version numbers of your dependencies in package.json (i.e. removing all the ^s) and run under Node 4.6.2, which is what I presume you were using back in February, I get this:

/Volumes/Geoffrey/Sites/es6-javascript-class-interop/class.es:2
	return class BaseClass {
	       ^^^^^

SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

With Node 7.1.0 and fixed versions of packages, I get this:

/Volumes/Geoffrey/Sites/es6-javascript-class-interop/node_modules/joe/out/lib/joe.js:186
        this.emitSerial('before', (function(_this) {
             ^

TypeError: this.emitSerial is not a function

and with the latest versions of packages (via npm-check-updates):

Can you still run this today? Do you mind please updating the package.json with the specific version of Node, and specific versions of packages, that work for you?
