推荐答案

您需要添加要由AppModule

imports: [RowComponent]

使用NO_ERRORS_SCHEMA，这是因为angular试图查找不存在的组件.

Use NO_ERRORS_SCHEMA, this is because angular is trying to find an component that doesn't exists.

CUSTOM_ELEMENTS_SCHEMA用于选择器名称中带有-的组件.

CUSTOM_ELEMENTS_SCHEMA is for components with a - in the selector name.
