javascript - ng2-chart lib 没有导出成员，例如：ChartDataSetBase 等

问题描述

我正在尝试根据以下本教程实施财务图表：

https://valor-software.com/ng2-charts/

我还在这里找到了这个实现的一个例子： https ://stackblitz.com/edit/ng2-charts-financial-template?file=src%2Fchartjs-chart-financial%2Fchartjs-chart-financial.js

我在 VSC 中创建了一个新的 Angular 应用程序。我所做的与 stackblitz 中的示例完全相同。但是，当我运行ng serve时，出现以下错误：

ERROR in ./src/app/app-chart-config.ts 4:0-222
"export 'BaseChartMetaConfig' was not found in 'ng2-charts'

ERROR in ./src/app/app-chart-config.ts 4:0-222

ERROR in ./src/app/app.component.ts
Module not found: Error: Can't resolve 'chartjs-adapter-luxon' in 'E:\Chartjs\financial3\ng2-charts-financial-template\src\app'

问题似乎出在文件app-chart-config.ts上。

import * as ng2Charts from '../../node_modules/ng2-charts';
import { AppChartMetaConfig } from './app-chart-meta-config';

// Generated by ng2-charts-schematics. This file should not need any modification.
// To add new features to the chart.js module, edit the file 'app-chart-meta-config.ts`

export * from './app-chart-meta-config';
export {
  ChartsModule,
  Color,
  Colors,
  defaultColors,
  ChartDataSetsBase,
  ChartDataSetsUnion,
  BaseChartMetaConfig,
  ChartMetaConfig,
  LegacyMetaConfig,
  PromiscuousMetaConfig,
  ScaleUnion,
  ThemeService,
  BaseChartDirective,
  Label,
} from 'ng2-charts';

export type AngularChart = ng2Charts.AngularChart<AppChartMetaConfig>;
export type ChartOptions = ng2Charts.ChartOptions<AppChartMetaConfig> &
  AppChartMetaConfig['additionalOptions'];
export type ChartDataSetsBar = ng2Charts.ChartDataSetsBar<AppChartMetaConfig>;
export type ChartDataSetsLine = ng2Charts.ChartDataSetsLine<AppChartMetaConfig>;
export type ChartDataSetsDoughnut = ng2Charts.ChartDataSetsDoughnut<
  AppChartMetaConfig
>;
export type ChartDataSetsRadar = ng2Charts.ChartDataSetsRadar<
  AppChartMetaConfig
>;
export type ChartDataSetsBubble = ng2Charts.ChartDataSetsBubble<
  AppChartMetaConfig
>;
export type ChartDataSetsScatter = ng2Charts.ChartDataSetsScatter<
  AppChartMetaConfig
>;
export type MultiDataSet = ng2Charts.MultiDataSet<AppChartMetaConfig>;
export type SingleDataSet = ng2Charts.SingleDataSet<AppChartMetaConfig>;
export type ChartType = ng2Charts.ChartType<AppChartMetaConfig>;
export type LinearScale = ng2Charts.LinearScale<AppChartMetaConfig>;
export type LogarithmicScale = ng2Charts.LogarithmicScale<AppChartMetaConfig>;
export type CategoryScale = ng2Charts.CategoryScale<AppChartMetaConfig>;
export type CartesianScale = ng2Charts.CartesianScale<AppChartMetaConfig>;
export type RadialScale = ng2Charts.RadialScale<AppChartMetaConfig>;
export type RadialLinearScale = ng2Charts.RadialLinearScale<AppChartMetaConfig>;

我的 app.module.ts：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { ChartsModule } from 'ng2-charts';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, AppRoutingModule, ChartsModule],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}

我的 package.json

    "ts-node": "~8.3.0",
    "tslint": "~6.1.0",

  }
}

似乎它在 ng2 图表中缺少一些导出。有人知道如何解决这个问题吗？

提前致谢！

干杯，马塞洛
