Ошибка сборки Sweetpacker2 Typescript Webpack

Question

Не могу понять, почему я получаю ошибки, когда запускаю стандартную команду "webpack". Я могу нормально скомпилировать мой машинописный текст, если удаляю « SweetAlert2 ». Любая помощь и свежие глаза очень ценятся.

Это шаги, которые я выполнял для получения ошибок компиляции.

1. npm установить sweetalert2
2. добавить ссылку на набор текста в мой файл машинописи
3. импортная ласточка из sweetalert2
4. вызов функции "swal" в верхней части моего машинописного файла в операторе jQuery ready
5. запустить команду "webpack"

Я получаю приведенную ниже ошибку в командном окне

ERROR in ./node_modules/sweetalert2/dist/sweetalert2.all.js
