npm run error реагирует на js

Question

Я учу ReactJS. Установка была завершена, но когда я запускаю эту команду npm, я получаю следующую ошибку.

     me@R-SOFT-85:/var/www/reactjsbasics$ npm run build
         > reactjsbasics@1.0.0 build /var/www/reactjsbasics
    > webpack -d && cp src/index.html dist/index.html && webpack-dev-server --content-base src/ --inline --watch

    /var/www/reactjsbasics/node_modules/webpack/bin/convert-argv.js:487
            throw new Error("'output.filename' is required, either in config file or as --output-filename");
            ^

    Error: 'output.filename' is required, either in config file or as --output-filename

Похоже, вы забыли экспортировать свой конфиг

// webpack.config.js

var config = {
 ...

}; 

// you need to export config object
module.exports = config
