'PlotlyModule' does not appear to be an NgModule class.

首先，使用 issue 中列出的 Angular 17 和 angular-plotly.js 4.0.4 版本重现 NG6002 错误。检查 app.module.ts 和 node_modules/angular-plotly.js/lib/plotly.module.d.ts，然后验证无需 Ivy 兼容性错误即可导入 PlotlyModule。

We are experiencing an issue when using angular-plotly.js and Angular17 saying that "'PlotlyModule' does not appear to be an NgModule class."

Error

error NG6002: 'PlotlyModule' does not appear to be an NgModule class.

176     PlotlyModule,
        ~~~~~~~~~~~~

  node_modules/angular-plotly.js/lib/plotly.module.d.ts:1:22
    1 export declare class PlotlyModule {

    This likely means that the library (angular-plotly.js) which declares PlotlyModule is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

app.module.ts

import * as PlotlyJS from 'plotly.js-dist-min';
import { PlotlyModule } from 'angular-plotly.js';
PlotlyModule.plotlyjs = PlotlyJS;

@NgModule({
  declarations: [
    ...,
  ],
  imports: [
    ...,
    PlotlyModule,
    ...,
]
});

Is there something that can be done that will enable this to work?
