Microsoft.AspNetCore.SpaServices由于节点模块map.d.ts而失败

Question

Angular v6.1.10 | ASP.Net Core v2.2.102

---

我正在使用ASP.NET Core和Angular应用上的填充下拉列表构建引导表单，当我尝试运行dotnet run时，它失败了：

  

失败：Microsoft.AspNetCore.SpaServices [0]

出现以下错误：

  

node_modules / rxjs-compat / add / operator / map.d.ts（4,9）中的错误：错误   TS2717：后续属性声明必须具有相同的类型。   属性“地图”的类型必须为“任何”，但此处的类型为“（this：   可观察的项目：（值：T，索引：数字）=> R，thisArg ?:任何）   =>可观察...'。

在此过程中的任何指导都是值得的。

Answer 1

已通过导入Observable import { Observable } from 'rxjs/Observable';解决，并将 porto.service.ts 中的getPortos更改为

getPortos(): Observable<any[]> {
    return this.HttpClient.get<any[]>('/api/portos')
}
