如何解决Angular 12 - 不可分配给类型 ''[number, number]？

我正在 Angular 12 中试用 ngx-charts 库，但我一直遇到这个问题：

类型 ''any[]'' 不能分配给类型 ''[number,number]''。

目标需要 2 个元素，但源可能更少。

我不知道错误是什么意思。

代码如下：

HTML：

<ngx-charts-linear-gauge 
  [view]="view" 
  [scheme]="colorScheme" 
  [value]="value" 
  [prevIoUsValue]="prevIoUsValue" 
  (select)="onSelect($event)" 
  [units]="units"
>
</ngx-charts-linear-gauge>

ts：

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

@Component({
  selector: ''app-root'',templateUrl: ''./app.component.html'',styleUrls: [''./app.component.scss'']
})
export class AppComponent {

  single: any[];
  view: any[] = [400,400];
  colorScheme = {
    domain: [''#aae3f5'']
  };
  value: number = 43;
  prevIoUsValue: number = 70;
  units: string = ''counts'';

  onSelect(event) {
    console.log(event);
  }

}

关于错误意味着什么的任何想法，如何解决这个问题？

ts 配置代码是：

{
  "compileOnSave": false,"compilerOptions": {
    "baseUrl": "./","outDir": "./dist/out-tsc","forceConsistentCasingInFileNames": true,"strict": false,"noImplicitReturns": true,"noFallthroughCasesInSwitch": true,"sourceMap": true,"declaration": false,"downlevelIteration": true,"experimentalDecorators": true,"moduleResolution": "node","importHelpers": true,"target": "es2017","module": "ES2020","lib": [
      "es2018","dom"
    ]
  },"angularCompilerOptions": {
    "enableI18nLegacyMessageIdFormat": false,"strictInjectionParameters": true,"strictInputAccessModifiers": true,"strictTemplates": true
  }
}

解决方法

// use as const so that typescript will infer the type [number,number] instead of number[]
view = [400,400] as const;

view: [number,number] = [400,400];
