我无法在angular 12项目的app.module.ts中导入ChartsModule。我试图导入它，但它只显示NgChartsModule，因为它的图表的一些功能不工作。这里有一些我收到的错误。

./src/app/reports/reports.component.ts:42:8-33 - Error: export 'monkeyPatchChartJsTooltip' (imported as 'monkeyPatchChartJsTooltip') was not found in 'ng2-charts' (possible exports: BaseChartDirective, NgChartsConfiguration, NgChartsModule, ThemeService, baseColors)

我试着从文档中搜索，但它没有提到这种错误。这里是我为此复制的文档的链接

和

我做了所有的步骤提到这里顺便说一句
