throw new InitializationError()

After added to webpack and run, I have error:

I also meet this error.

[gajus]

The error originates from within Prepack, i.e. it is nothing to do with prepack-webpack-plugin. I haven't had time to have a look whether there is a way to pull additional information about the error. As it is, it is not very useful and barely says that Prepack cannot work with your codebase.

I get this error as well if I use this plugin before uglify plugin, could be related to #14

[iHaiduk]

When I to disable uglify plugin, I have next error message

+1 I'm facing the same issue.

[iHaiduk]

I opened discus on main page of plugin: facebookarchive/prepack#590

I just want to check if people think this is the cause of my error:

[btiwaree]

@wookoouk your error seems related to improper require statement.
If you do: const PrepackWebpackPlugin = require('prepack-webpack-plugin').default;
instead of just require('prepack-webpack-plugin'), it should work.
See the second part of example #here.

[doomedramen]

@btiwaree I made this change and it gave me the error described above.

##Code

const path = require('path');
const webpack = require('webpack');
const PrepackWebpackPlugin = require('prepack-webpack-plugin').default;
module.exports = {
    entry: {
        app: [
            path.resolve(path.join(__dirname, "public", "js", 'app.jsx'))
        ],
    },
    watch: true,
    module: {
        loaders: [
            {
                test: /.jsx?$/,
                loader: 'babel-loader',
                exclude: /node_modules/,
                query: {
