You most likely have a 4.x babel-runtime
. Please remove your node_modules
folder and npm install
again.
from babel-loader.
@sebmck tried that already and also did a npm cache clean
from babel-loader.
Not sure what's causing this then:
$ node
> require("babel-runtime/core-js")["default"].Object.defineProperty
[Function: defineProperty]
from babel-loader.
@sebmck I think the problem might be a compatibility issue with iojs. Switched to node 0.12.x and it works now.
from babel-loader.
$ iojs
> require("babel-runtime/core-js")["default"].Object.defineProperty
[Function: defineProperty]
from babel-loader.
@sebmck never mind It's still happening in both. I still get the error with the simple example below, but if I remove the constructor
function the error is gone.
- babel-loader: 5.0.0
- babel-core: 5.1.10
- babel-runtime: 5.1.10
- react: 0.13.1
index.js
import React from 'react';
class MyComponent extends React.Component {
constructor(props) {
super(props);
}
render() {
return <div> test </div>;
}
}
React.render(<MyComponent/>, document.getElementById('main'));

here is a jsfiddle to demo the error https://jsfiddle.net/euforic/5vjqabv3/474/
from babel-loader.
Can you verify that you're using the latest babel-runtime
please. cc @zloirock
from babel-loader.
@sebmck emm? In last example I don't see core-js
, only helpers.
from babel-loader.
@zloirock Look at the jsfiddle, the error is being thrown on the line module.exports = __webpack_require__(10).core.Object.keys;
.
from babel-loader.
Interesting. I don't test it with webpack. I will investigate the problem in the evening.
from babel-loader.
Looks like bug it config. Webpack run runtime
transformer on core-js
files.
from babel-loader.
Try changing your exclude
filter to /node_modules/
.
from babel-loader.
@sebmck yep that fixes it. Thanks for all the help!
