Tôi có một dự án Angular2 nhỏ dựa trên dự án Angular2 Seed mà tôi đang cố gắng nâng cấp lên Angular2 RC5.
Dự án của tôi có một vài tính năng, một trong số chúng được gọi là home
. Thành phần nhà sử dụng một thành phần con được gọi là create-report-card-form
. Tôi đã khai báo cả home và create-report-card-form
các thành phần trong home.module
(xem mã bên dưới) và gặp lỗi này :
Từ chối Promise chưa được xử lý: Lỗi phân tích cú pháp mẫu: Không thể liên kết với 'currentReportCardCount' vì nó không phải là thuộc tính đã biết của 'create-report-card-form'.
- Nếu 'create-report-card-form' là một thành phần Angular và nó có đầu vào 'currentReportCardCount', thì hãy xác minh rằng nó là một phần của mô-đun này.
