JavaScript-错误：模板解析错误：无法绑定到“选项”,因为它不是“图表”的已知属性

嗨,我有以下组件,

import {Component, OnInit, Input} from '@angular/core';
import { Observable } from 'rxjs/Rx';

@Component({
    selector: 'chart',
    templateUrl: 'app/comps/chart.html',
    providers: [],
})
export class ChartComp {

    constructor() {
        this.options = {
            title : { text : 'simple chart' },
            series: [{
                data: [29.9, 71.5, 106.4, 129.2],
            }]
        };
    }
    options: Object;
}

和模块文件：

import { ChartModule } from 'angular2-highcharts';

@NgModule({
    imports: [ChartModule.forRoot(require('highcharts'))],

declarations: [Chart],
exports: [Chart]})

export class modulefile {
....
}

和html文件

<chart [options]="options"></chart>

我有一个示例页面,该页面实现了此组件,

import { Component } from '@angular/core';
import { Router } from '@angular/router';

@Component({
    selector: 'example-chart',
    templateUrl:'app/comps/chart/example-chart.html',
    providers: [],
})


export class ExampleChart{

    constructor(

    ) {
        this.options = {
            title : { text : 'simple chart' },
            series: [{
                data: [29.9, 71.5, 106.4, 129.2],
            }]
        };
    }
    options: Object;
}

和html,

<chart [options]="options"></chart>

它的选项是传递给html的配置.但不确定为什么会收到这个奇怪的错误,

EXCEPTION: Uncaught (in promise): Error: Template parse errors:
Can't bind to 'options' since it isn't a kNown property of 'chart'.
1. If 'chart' is an Angular component and it has 'options' input, then verify that it is part of this module.
2. If 'chart' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schemas' of this component to suppress this message.

我尝试为选项添加@Input.然后我得到一个DI错误.有想法吗？提前致谢.

解决方法:

您需要将其作为输入,以便能够使用属性绑定与其绑定：

@input()
options: Object;
