npm test - ERROR [preprocess]: Can not load "webpack"!

[escapedcat]

I checked out the latest master (after the webpack2 update).

When I run npm test I get this and some more error messages:

> angular-webpack-workflow@1.1.0 test /home/hannes/data/www/angular-webpack
> karma start

Anyone else is having the same issue?
Did I miss something?
I'm running node version 5.8.0 on Linux Mint.

This seems to be related to Can not load 'webpack' - issue with v2.1.0 #210.

Changing these two parts in webpack.config.js make the tests work but they fail due to missing css:

  if (!isTest) {
    config.entry = {
      app: './src/app/app.js'
    };
  };

// loader: isTest ? 'null' : ExtractTextPlugin.extract({
//   fallbackLoader: 'style-loader',
//   loader: [
//     {loader: 'css-loader', query: {sourceMap: true}},
//     {loader: 'postcss-loader'}
//   ],
// })

@escapedcat i've experiencing this bug too. i will look into it right now.

@escapedcat can you try to check if now the problem is gone also for you? thanks.

Thanks @phra, works!

And I learned that:

• void can be used in that way
• null-loader is an actual thing. I didn't see that before

Thanks for that as well!

@escapedcat happy to help! 👍
