javascript - ng2-chart 与 Angular 4 : Can't bind to 'data' since it isn't a known property of 'canvas'

Question

这个想法是将 chart.js 与 Angular 4 和 ng2-charts 结合使用。我正在使用示例 here ，但我无法让它工作。

我收到以下错误消息:

Can't bind to 'data' since it isn't a known property of 'canvas'

我已经将其导入到 app.module.ts 中，因为大多数帖子都提示此错误。我有什么遗漏的吗？

...组件.html:

<div style="display: block">
    <canvas baseChart
        [data]="data"
        [labels]="labels"
        [chartType]="type">
    </canvas>
</div>

...组件.ts

...
labels:string[] = ['Download Sales', 'In-Store Sales', 'Mail-Order Sales'];
data:number[] = [350, 450, 100];
type:string = 'doughnut';
...

index.html:

<script src="lib/chart.js/dist/chart.js"></script>

app.module.ts:

import { ChartsModule } from 'ng2-charts/ng2-charts';
imports: [
    ...
    ChartsModule,
    ...
],

系统.js

map: {
    ...
    'ng2-charts': 'npm:ng2-charts/bundles'
},
packages: {
    ...
    'ng2-charts': {
         defaultExtension: 'js'
    }
}

package.json:

Answer 1

经过几个小时的尝试和错误，我成功了。我更改了以下内容:

app.module.ts:

import { ChartsModule } from 'ng2-charts';

系统.js:

map: {
    ...
    'ng2-charts': 'npm:ng2-charts/bundles'
},
packages: {
    ...
    'ng2-charts': {
         main: 'ng2-charts.umd.min.js',
         defaultExtension: 'js'
    }
}
