Cannot set property 'parentContext' of undefined

[feross]

According to #70, this error is caused by react-lite lacking support for ES6 class syntax.

Can you please add support for that? Without it, it's impossible for most modern React codebases to take advantage of react-lite.

Got it, I will try to fixed this problem as soon.

When I tryed to reproduce this problem, I found that babel has been resolved it.

before

function App(props, context) {
        _classCallCheck(this, App);

        var _this = _possibleConstructorReturn(this, Object.getPrototypeOf(App).call(this, props, context));

        _this.state = {
            count: 0
        };
        return _this;
    }

after

    function App(props, context) {
        _classCallCheck(this, App);

        var _this = _possibleConstructorReturn(this, (App.__proto__ || Object.getPrototypeOf(App)).call(this, props, context));

        _this.state = {
            count: 0
        };
        return _this;
    }

Upgrade babel to lastest version.

I am using buble, so that might explain the issue. Sorry for the trouble.

how to config .babelrc?

my config below:
{ "presets": ["react", "es2015"], "plugins": ["transform-es2015-classes"] }
still show "Cannot set property 'parentContext' of undefined".
thanks
