Uncaught Error: addComponentAsRefTo(...): Only a ReactOwner can have refs.

[berthelol]

I have this error when I try to use react-progressbar.js in my react App.

I figured it was because react was called inside react-progressbar.js

I don't know how to fix it. I tried using alias and putting react in externals but nothing worked...
Here is my webpack.

const webpack = require('webpack');
const path = require('path');
module.exports = {
  entry: [
    './src/index.js'
  ],
  output: {
    path: path.join(__dirname, '/public/'),
    publicPath: '/',
    filename: 'bundle.js'
  },
  plugins: [
    new webpack.ProvidePlugin({
      WaveSurfer: 'wavesurfer.js'
    })
  ],
  module: {
    loaders: [{
      exclude: /node_modules/,
      loader: 'babel',
      query: {
        presets: ['react', 'es2015', 'stage-1']
      }
    },
    {test: /\.(jpe?g|png|gif|svg)$/i,
        loaders: [
          'file?hash=sha512&digest=hex&name=[hash].[ext]',
          'image-webpack?bypassOnDebug&optimizationLevel=7&interlaced=false'
        ]}
  ]
  },
  resolve: {
    extensions: ['', '.js', '.jsx'],
    alias: {
      wavesurfer: require.resolve('wavesurfer.js')
    }
  },
  devServer: {
    historyApiFallback: true,
    contentBase: './'
  }
};

And here is my package.json

It should happen if u using React 16, with multiple React version installed.
I think the possible solution should be:

1. Update the alias in webpack.config:

alias: {
  react: path.resolve('node_modules/react'),
  'react-dom': path.resolve('node_modules/react-dom')
},

2. Update the code, replace the React.CreateClass > var createReactClass = require('create-react-class');
