Styleguidist: Module not found errors

Question

I am trying to get Styleguidist to run in an existing React environment.

When running

yarn styleguidist build 

I get errors like this:

My styleguide.config.js:

module.exports = {
  components: 'src/components/**/[A-Z]*.js',
  webpackConfig: {
    module: {
      rules: [
        // Babel loader, will use your project’s babel.config.js
        {
          test: /\.jsx?$/,
          exclude: /node_modules/,
          loader: 'babel-loader',
          query: {
            presets: ['@babel/preset-env', '@babel/preset-react'],
          },
        },
        // Other loaders that are needed for your components
        {
          test: /\.css$/,
          use: ['style-loader', 'css-loader']
        }    
      ]
    }
  }
}

1. How can I help Styleguidist to resolve the imports inside a component?
2. How can I prevent Styleguidist to search inside the
   node_modues folder? I thought "exclude: /node_modules/" does that already?
