angular - amcharts4 没有用 angular 6 编译

Question

在包含 amcharts4 时，我在编译我的应用程序时遇到了问题。我只是安装了 amcharts4 npm 包，并试图在我创建的组件中使用它。我是否遗漏了 CLI 配置的某些内容？

ERROR in node_modules/@amcharts/amcharts4/.internal/core/utils/Object.d.ts(60,117): error TS2536: Type 'Key' cannot be used to index type 'Object'.
node_modules/@amcharts/amcharts4/.internal/core/utils/Object.d.ts(67,109): error TS2536: Type 'Key' cannot be used to index type 'Object'.
node_modules/@amcharts/amcharts4/.internal/core/utils/Object.d.ts(76,116): error TS2536: Type 'Key' cannot be used to index type 'Object'.
node_modules/@amcharts/amcharts4/.internal/core/utils/Type.d.ts(25,32): error TS2304: Cannot find name 'Extract'.

我的 typescript :

import { Component, NgZone } from "@angular/core";
import * as am4core from "@amcharts/amcharts4/core";
import * as am4charts from "@amcharts/amcharts4/charts";
import am4themes_animated from "@amcharts/amcharts4/themes/animated";

am4core.useTheme(am4themes_animated);


@Component({
  selector: 'app-am-charts',
  templateUrl: './am-charts.component.html',
  styleUrls: ['./am-charts.component.css']
})
export class AmChartsComponent {

}

根据 this issue this newer closed issue和我们的 angular integration documentation ，请确保您的 tsconfig.json 中包含以下内容，因为 AmCharts 4 当前不支持严格模式:

{
    "compilerOptions": {
        "strictNullChecks": false,
        "strictFunctionTypes": false
    }
}

除此之外，请确保您至少使用 TypeScript 版本 2.7 2.8 但不是 3.x，因为它尚不受支持。
