я хотел бы добавить в свой проект боковую панель nativescript, но я получаю сообщение об ошибке

 An uncaught Exception occurred on "main" thread.
Calling js method onClick failed
Error: Building UI from XML. @home/home-page.xml:15:9
 > Module 'nativescript-ui-sidedrawer' not found for element 'nativescript-ui-sidedrawer:RadSideDrawer'.
   > Class extends value undefined is not a constructor or null
  

я работал с ним раньше в предыдущем проекте, и я не получал эту ошибку

ниже приведен мой XML-код

Пожалуйста, помогите, спасибо

Ну, вы добавили боковой ящик в свой проект?

 tns plugin add nativescript-ui-sidedrawer
  

Да, это очевидно, но я допустил аналогичные оплошности 🙂
