TypeError: Super expression must either be null or a function, not undefined

dschinkel commented 6 years ago

Can't figure this out. I've done this many times, updated react projects from 15 to 16 including enzyme to the 16 adaptor and it's been fine. But for this project it's complaining. I updated react from 15 to 16. When I try running my mocha test for the first time I get:

function _inherits(subClass, superClass) { if (typeof superClass !== "function" && superClass !== null) { throw new TypeError("Super expression must either be null or a function, not " + typeof superClass); } subClass.prototype = Object.create(superClass && superClass.prototype, { constructor: { value: subClass, enumerable: false, writable: true, configurable: true } }); if (superClass) Object.setPrototypeOf ? Object.setPrototypeOf(subClass, superClass) : subClass.__proto__ = superClass; } /* eslint no-use-before-define: 0 */

I've setup enzyme like I always do which has worked fine in other react projects:

import React from 'react'
import Enzyme from 'enzyme';
import chai, { expect } from 'chai';
import { shallow, mount } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

Enzyme.configure({ adapter: new Adapter() });

This title is a duplicate of #1172. Is it perhaps the same issue?

Generally, this often occurs when there's a circular dependency somewhere; I'm not sure where there would be one here.

yea I took a look at that issue as well. Let me investigate more. thx

eh just needed to install "babel-core". thought I did already but didn't.
