Ошибка сборки Angular 7 + Ionic 4 «TypeError: невозможно прочитать свойства неопределенного (чтение« вида »)»

Мне нужна помощь с проблемой создания моего приложения Angular 7 и Ionic 4...

Если я запускаю команду ng build --prod, я получаю следующую ошибку:

ERROR in ./node_modules/ionic4-auto-complete/fesm5/ionic4-auto-complete.js
Module build failed (from ./node_modules/@angular-devkit/build-optimizer/src/build-optimizer/webpack-loader.js):
TypeError: Cannot read properties of undefined (reading 'kind')

Это мой файл пакет.json:

Я гуглю эту проблему уже несколько часов и понятия не имею, что делать ... это мое первое приложение Angular + Ionic, поэтому я все еще учусь ... Я делаю что-то не так? Должен ли я использовать другую команду сборки?
