Я новичок в Ionic2. Я начал разработку в браузере, у меня было много проблем с внедрением модуля «crypto-js» и его использованием, но, наконец, я его получил.

Теперь я установил платформу Android в проекте, и теперь я получаю эту ошибку во время сборки:

Эта ошибка появляется только после запуска «ionic build android» или «ionic run android», но с «ionic serve» все в порядке. Я погуглил, но я не нашел никого с этой проблемой с crypto-js или другим модулем.
