Установил webpack, подключил webpack.config с базовыми настройками, но при вводе команды webpack выбрасывает ошибку - **webpack : The term 'webpack' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:1
