Ошибка загрузки трансформатора
РЕШЕНИЕ
Так что на самом деле возникли две проблемы, с которыми я столкнулся при создании приложения. Первой была ошибка трансформатора. Однако в комментариях к этому сообщению показано, как исправить эту ошибку (удалите.pub-cache в домашнем каталоге, удалите.pub в каталоге проекта, а затем запустите pub get и восстановление кеша pub).
Однако вторая проблема, с которой я столкнулся, заключалась в том, что у ножниц есть несколько внешних зависимостей, о которых я забыл. Когда я отформатировал свой компьютер, эти зависимости были удалены. После того, как я установил их, я смог построить проект снова.
ОРИГИНАЛЬНЫЙ ВОПРОС
В настоящее время я сталкиваюсь с проблемой при запуске pub build --mode=debug --verbose где трансформатор angular2 не загружается.
Я отформатировал свою машину прошлой ночью и переустановил все. Сборка работала нормально до того, как я отформатировал, однако сейчас она терпит неудачу. Поэтому я понятия не имею, что может быть причиной этого.
Я попытался удалить.pub-cache и вытащить обратно зависимости. Я тоже пробовал бегать pub cache rebuild --verbose и ничто не кажется неправильным / необычным. Я не уверен, что мне не хватает.
Ниже приведен полный вывод вышеприведенной команды.
