Object.defineProperty called on non-object about rewire

[jhnns]

Could you find out what traceur is trying to do?

Especially this line:

    at Function.defineProperty (/mnt/sdb1/code/dev/sane/node_modules/traceur/bin/traceur.js:257:7)

Currently I can't see that rewire has something to do with it.

All it is doing is checking for a shim and then calling the object's normal defineProperty function.

253  function defineProperty(object, name, descriptor) {
254        if (isShimSymbol(name)) {
255          name = name[symbolInternalProperty];
256        }
257        $defineProperty(object, name, descriptor);
258        return object;
259      }

I'm not sure why this would be a problem in Treaeur, because everything works fine as long as I don't use rewire. Is there anything else I can do to try to help troubleshoot?

You could create a minimal test-case that produces the error. And you could also check what value targetModule.id is here.

Alright, I'll try to put something together in the next few days.

OK, it seems that this occurs if the module being rewired exports a string or a variable with a string value. Is that not a supported use of rewire?

[jhnns]

@IanVS are you using mocha as test runner?

Sorry, I've over-read this.

Unfortunately yes, rewiring modules that export a primitive value is not possible, because the current API needs to attach methods like __set__ and __get__ to the export. I need to clarify that in my readme.
