谁能指导一下解决这个问题。是库问题还是版本不兼容错误。

Answer 1

您的 NGRX 版本是 10

请查看 v7 的迁移文档。

ofType 现在是可管道运算符，因此现在正确使用是：

https://ngrx.io/guide/migration/v7

 this.actions$.pipe(
    ofType(fromCuser.LOAD_CUSER),
    ...

迁移到 Angular 10 后，出现错误 - 错误 TS2339：属性 'ofType' 在类型 'Actions<Action>' 上不存在

After Migrating to Angular 10, I am getting error - error TS2339: Property 'ofType' does not exist on type 'Actions<Action>'
