无法绑定到属性，因为它不是Angular中“ component”的已知属性

标签： angular

我正在Angular 7中构建一个共享组件。共享组件是模式窗口。当我在特定模块中使用共享组件时，它工作正常，但如果将共享组件添加到共享模块中，则会给我一个错误。如您在代码中看到的，我创建了一个共享模块，该模块导出共享组件。我已将其添加到AppModule的声明中。然后，将其导入到另一个模块中，在该模块中，需要使用模式窗口作为其组件之一。

我想念什么？

错误

Can't bind to 'modalSize' since it isn't a known property of 'shared-modal'.
1. If 'shared-modal' is an Angular component and it has 'modalSize' input, then verify that it is part of this module.
2. If 'shared-modal' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("

@Input批注应直接放在_moduleSize的设置器上：

private _modalSize = 1; // 1:normal, 2: medium, 3: large
public get modalSize() {
    return this._modalSize;
}
@Input()
public set modalSize(value) {
    this._modalSize = value;
}

以前，注释仅将private参数声明为输入。但是，由于它是私有的，因此它是不可见的。将其放在公共设置器上，将使您可以在其他地方正确使用它。
