Как решить проблему с loader в webpack 4?

Перепробывал кучу вариантов. Помогите исправить ошибку при выполнении команды npm run build.
В папку dist ничего не ложит, css файлы создаёт внутри папки с sass файлом только при запуске run dev.

[0] ./src/index.js 26 bytes {0} [built]
[1] ./src/sass/main.sass 185 bytes {0} [built] [failed] [1 error]

ERROR in ./src/sass/main.sass 2:13
Module parse failed: Unexpected token (2:13)
You may need an appropriate loader to handle this file type.

webpack.config.js

let path = require('path');
let ExtractTextPlugin = require('extract-text-webpack-plugin');

module.export = {
    entry: ['webpack/hot/dev-server' ,  './src/main.js'],
    output: {
        path: path.resolve(__dirname, 'dist'),
        publicPath: __dirname + '/dist',
