Radium не создает CSS с помощью Webpack 4

Question

Я пытаюсь обновить Webpack с v1 до v4. Я вижу созданный файл CSS, но он не имеет встроенного CSS из Radium.

Вот мой конфиг вебпак

var autoprefixer = require('autoprefixer');
var webpack = require('webpack');

var shouldUseRelativeAssetPaths = publicPath === './';
var publicUrl = publicPath.slice(0, -1);
var env = getClientEnvironment(publicUrl);

Я не уверен, что я здесь делаю неправильно. Для меня это выглядит так: мне нужно изменить использование Radium в соответствии с новой конфигурацией Webpack.

Я уже внес изменения в соответствии с документацией Radium, но безуспешно.

Кто-то еще сталкивался с такой же проблемой. Пожалуйста, дайте мне знать.
