LeafletModule 无法解析为 Ivy 中的 NgModule 类

如何解决LeafletModule 无法解析为 Ivy 中的 NgModule 类

我正在使用 ngx-leaflet 开发一个有角度的项目。 在控制台运行ng serve后，出现如下错误：

Error: node_modules/@asymmetrik/ngx-leaflet/dist/leaflet/leaflet.module.d.ts:1:22 - error NG6002: Appears in the NgModule.imports of AppModule,but Could not be resolved to an NgModule class.

This likely means that the library (@asymmetrik/ngx-leaflet) which declares LeafletModule has not been processed correctly by ngcc,or 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 Check if a newer version of the library is available,and update if so.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.

1 export declare class LeafletModule {
                       ~~~~~~~~~~~~~

在app.module.ts中导入：

import { LeafletModule } from '@asymmetrik/ngx-leaflet';

也在 app.module.ts 的 @NgModule 中：

@NgModule({
  declarations: [
    ...
  ],imports: [
    ReactiveFormsModule,AngularFireModule.initializeApp(config),AngularFireAnalyticsModule,AngularFirestoreModule,AngularFireAuthModule,AngularFireStorageModule,AngularFireDatabaseModule,browserModule,AppRoutingModule,LeafletModule
  ],providers: [
    ...
  ],bootstrap: [AppComponent]
})

这是一个已知问题还是我只是遗漏了一些东西并搞砸了导入？

版本信息：

Angular CLI: 11.0.6
Node: 12.18.3
OS: darwin x64

Angular: 10.0.8
... animations,common,compiler,compiler-cli,core,forms
... platform-browser,platform-browser-dynamic,router
Ivy Workspace: Yes

来自 package.json：

"@asymmetrik/ngx-leaflet": "^8.1.0","leaflet": "^1.7.1",

解决方法

我将我的本地 angular 版本更新为 11.0.8，现在导入工作正常。除了将 rxjs 更新为 6.6.3 之外，没有其他任何更改，我怀疑这是否相关。 我想错误发生在 10.0.8 上。
