Webpack fails to load bootstrap v4.0.0-beta

I've recently made a config with webpack and bootstrap v4.0.0-alpha.6 which worked fine until today when I tried to change to v4 beta and now I can't seem to make it work properly :( I have this config:

webpack.config.js

entry: {
    app: "./src/app.js"
},
output: {
    path: path.resolve(__dirname, 'public'),
    filename: 'js/[name].js',
    hotUpdateChunkFilename: 'hot/hot-update.js',
    hotUpdateMainFilename: 'hot/hot-update.json'
},
module: {
    loaders: [
        { test: /\.js$/, exclude: /node-modules/, loader: 'babel-loader' },
        { test: /\.html$/, loader: 'raw-loader', exclude: /node_modules/ },
        {   test: /\.(css|scss|sass)$/,
            loader: ExtractTextPlugin.extract({
                fallback: "style-loader",
                use: ['css-loader', 'postcss-loader', 'sass-loader']
            }),
            exclude: /node_modules/
        }           
    ]
},
plugins: [
    new webpack.ProvidePlugin({ // inject ES5 modules as global vars
        $: 'jquery',
        jQuery: 'jquery',
        'window.jQuery': 'jquery',
        Popper: ['popper.js', 'default']
    }),
    new ExtractTextPlugin('/css/[name].css'),

in my app.js I have the require('bootstrap'); Now when I try to make build now I get an error:

ERROR in ./node_modules/bootstrap/dist/js/bootstrap.js
Module build failed: ReferenceError: Unknown plugin "transform-es2015-modules-strip" specified in "E:\\Documente\\Work\\wordpress\\wordpressSite\\wp-content\\themes\\bsTheme\\node_modules\\bootstra
p\\.babelrc" at 0, attempted to resolve relative to "E:\\Documente\\Work\\wordpress\\wordpressSite\\wp-content\\themes\\bsTheme\\node_modules\\bootstrap"

The issue seems to be here in bootstrap/.babelrc

{
    "presets": [
        [
            "es2015",
            {
                "loose": true,
                "modules": false
            }
        ]
    ],
    "plugins": [
        "transform-es2015-modules-strip"
    ]
}

I tried to go in bootstrap directory and ran: npm install (i don't know why I should do that since I already have my own config for bable/autoprefixer) I already have babel-core, babel-loader, babel-preset-es2015 installed in my own package.json I installed transform-es2015-modules-strip and ran build again:

ERROR in ./node_modules/bootstrap/dist/js/bootstrap.js
Module not found: Error: Can't resolve 'jquery' in 'E:\Documente\Work\wordpress\wordpressSite\wp-content\themes\bsTheme\node_modules\bootstrap\dist\js'
 @ ./node_modules/bootstrap/dist/js/bootstrap.js 1:0-17
 @ ./src/app.js

ERROR in ./node_modules/bootstrap/dist/js/bootstrap.js
Module not found: Error: Can't resolve 'popper.js' in 'E:\Documente\Work\wordpress\wordpressSite\wp-content\themes\bsTheme\node_modules\bootstrap\dist\js'
 @ ./node_modules/bootstrap/dist/js/bootstrap.js 1:0-20
 @ ./src/app.js

So I tried and installed jquery and popper in my project as dev dependency...got rid of the jquery error but..:

ERROR in ./node_modules/bootstrap/dist/js/bootstrap.js
Module not found: Error: Can't resolve 'popper.js' in 'E:\Documente\Work\wordpress\wordpressSite\wp-content\themes\bsTheme\node_modules\bootstrap\dist\js'
 @ ./node_modules/bootstrap/dist/js/bootstrap.js 1:0-20
 @ ./src/app.js

Out of ideas...and this seems over complicated...I can't seem to know what I'm doing wrong, the only thing I can come up with is to get the bootstrap.js file put it directly with my other js files... long post but I wanted to be as specific as possible.

What should I do to make it work again, I would really appreciate some help. Thank you
